Montgomery County Military Records

See Also Military Records in Ohio

The uses and value of military records in genealogical research for ancestors who were veterans are obvious, but military records can also be important to re-searchers whose direct ancestors were not soldiers in any war. The fathers, grandfathers, brothers, and other close relatives of an ancestor may have served in a war, and their service or pension records could contain information that will assist in further identifying the family of primary interest. Due to the amount of genealogical information contained in some military pension files, they should never be overlooked during the research process. Those records not containing specific genealogical information are of historic value and should be included in any overall research design.

The Repositories in this section are Archives, Libraries, Museums, Genealogical and Historical Societies. Many County Historical and Genealogical Societies publish magazines and/or news letters on a monthly, quarterly, bi-annual or annual basis. Contacting the local societies should not be over looked. State Archives and Societies are usually much larger and better organized with much larger archived materials than their smaller county cousins but they can be more generalized and over look the smaller details that local societies tend to have. Libraries can also be a good place to look for local information. Some libraries have a genealogy section and may have some resources that are not located at archives or societies. Also, take a special look at any museums in the area. They sometimes have photos and items from years gone by as well as information of a genealogical interest. All these places are vitally important to the family genealogist and must not be passed over.

Montgomery County Church & Cemeteries

See Also Church & Cemetery Records in Ohio

There are many churches and cemeteries in Montgomery County. Some transcriptions are online. A great site is the Montgomery County Tombstone Transcription Project.

Religion in Ohio was an early and important factor in settlement. The first Moravian mission was established in 1772. Presbyterians and Quakers were in the state at an early date, the latter having established forty-three monthly meetings and settlements between 1801 and 1883. The Presbyterians founded seventeen towns between 1784 and 1799. Baptists, Congregationalists, several reformed groups, Lutherans, Disciples of Christ, United Brethren, Methodists, and Catholics arrived prior to 1850. By 1890 the latter two denominations were the largest in the state. The Methodist circuit in Ohio was organized in 1798, with circuit riders traveling from log cabins to camp meetings across the territory. In 1831 the Church of Jesus Christ of Latter-day Saints migrated from New York to Kirtland in Lake County. No thorough survey exists of any of the holdings of individual churches in Ohio, although many are on microfilm through the FHL. The Ohio Genealogical Society is presently undertaking a church records survey.

According to the Ohio Genealogical Society, the majority of Ohio counties have published cemetery records in one form or another. They suggest contacting local societies or one of the major genealogical libraries in the state.

Extended History

 

On March 24, 1803, the Ohio government authorized the creation of Montgomery County. Residents named the county in honor of Richard Montgomery, a hero of the American Revolution. Previously, the county had been parts of Ross and Hamilton Counties. Wilbur and Orville Wright owned a bicycle shop in Dayton, the county seat, during the late nineteenth and early twentieth century. It was here that the Wrights developed their airplane, the first one to fly successfully.

Montgomery County is located in western Ohio. It is predominantly rural, with seventeen percent of the county’s 462 square miles consisting of urban areas. With a population of 166,179 people, Dayton was the county’s largest community in 2000. The county experienced a 2.6 percent decline in population between 1990 and 2000, reducing the total number of residents to 559,062. The principal reason for this decline was a desire of some residents to escape the busyness of Dayton. The county averages 1,210 people per square mile.

Montgomery County flourished during the nineteenth century. With the completion of the Miami and Erie Canal in 1829, connecting Dayton to Cincinnati, the county residents thrived. In addition, nine turnpikes connected Dayton to other areas of the state. Because of its status as a transportation hub, Montgomery County was heavily involved in Ohio’s early industrialization. By the late 1800s, the county had become the center of many types of industry. There were many newspapers and journals that fueled the publishing industry. Many of these publications dealt with either religious issues or agricultural interests. Some examples include Christian World, Young Catholic Messenger, Ohio Bible Teacher, as well as Farmer’s Home, the Ohio Swine Journal, and the Ohio Poultry Journal. Many other industries were related to agriculture, including mills and numerous companies manufacturing farm implements. Among the best known in the nineteenth century was the Buckeye Mower and Reaper Company. In the 1880s, John Patterson opened the National Cash Register Company in Dayton.

Today, service industries, such as health care and tourism, retail positions, and manufacturing businesses are Montgomery County’s largest employers. Government ranks a distant fourth. Most government employees work at Wright-Patterson Air Force Base. In 1999, the per capita income in the county was 28,113 dollars, with 11.1 percent of the people living in poverty.

In 1796, Israel Ludlow founded the town of Dayton along the Miami River near the mouth of the Mad River.It was located near the Symmes Purchase. By the end of that same year, more than forty log cabins and frame houses existed in the community. Many of these original settlers believed that they had legally acquired the land, but disputes quickly arose over landownership due to poor surveying. Many residents ended up paying additional sums of money to become the official owners of their property. In addition to the disputed land claims, Dayton was built on a flood plain, and the community flooded numerous times in its early years.

When Ohio became a state in 1803, Dayton became the seat of Montgomery County. Beyond Dayton's initial growth, however, the town remained relatively small until the War of 1812. During this conflict, Dayton served as an embarkation point for American attacks on Canada and on British troops in the northwestern part of the United States. Both during and following the war, factories and mills quickly came into being, including a tobacco factory, textile mills, and several other establishments. Dayton boasted two banks by the 1810s as well. With the completion of the Miami and Erie Canal line in 1829 connecting Dayton to Cincinnati, the town continued to thrive. In addition, nine turnpikes connected Dayton to other areas of the state. By the 1840s, Dayton was one of the largest and wealthiest communities in Ohio.

Dayton was heavily involved in Ohio's early industrialization. By the late 1800s, the community had become a center of industry in Ohio. Many of Dayton's other industries were related to agriculture, including mills and numerous companies manufacturing farm implements. Among the best known in the nineteenth century was the Buckeye Mower and Reaper Company. In the 1880s, John Patterson opened the National Cash Register Company in Dayton. Because of the community's industries, workers began organizing in the 1800s as well. One of the first labor organizations in Ohio, the Mechanics' Association, was founded in 1813, and over the next century a number of labor unions organized.

Dayton was also a center for the newspaper and journal publishing industry in Ohio. Many of these publications dealt with either religious issues or agricultural interests. Some examples include Christian World, Young Catholic Messenger, Ohio Bible Teacher, as well as Farmer's Home, the Ohio Swine Journal, and the Ohio Poultry Journal. There were also German newspapers for the town's German settlers. The most famous literary figure from Dayton was Paul Laurence Dunbar. Widely acclaimed as the poet laureate of African Americans, Dunbar penned numerous novels and books of poetry in the late-nineteenth and early-twentieth centuries. The Ohio Historical Society currently maintains Dunbar's final home in Dayton as a state memorial.

In the twentieth century, Dayton continued to prosper. In the first decade, the city became known as the home of Wilbur and Orville Wright, the brothers who made the first successful airplane flight. The Flood of 1913, which created significant loss of life and property in Dayton, temporarily halted the city's growth, but the people of Dayton quickly rebounded.

During the Progressive Era of the late nineteenth and early twentieth centuries, Dayton became a center of political reform. Rejecting the control of corrupt city bosses who manipulated politics to serve their own interests, Dayton became the first larger city in the nation to do replace elected mayors with hired professional managers to run the city. Dayton residents believed that the possibility of being fired by the city council created an incentive for the city managers to perform their duties honestly.

In the 1920s, Dayton became a center of Ku Klux Klan activity in the state. Like other industrial cities such as Akron, anti-immigrant and anti-Semitic feelings in Dayton fueled Ku Klux Klan membership during that decade.

Dayton benefited economically from the growth of wartime industries during World War II, receiving approximately $1.7 billion in government defense contracts during the war. The city's economy has remained strong in the decades following the Second World War, despite a decline in many of its traditional industries.

In recent years, Dayton was most famous as the site of the Dayton Peace Accords in 1995.With the United States' support, the Serbs and Bosnians negotiated a peace settlement at nearby Wright-Patterson Air Force Base that led to a decline of ethnic violence in Bosnia.
