Where Was Dewitt S. Blackman born?

In yet another birthplace mystery, I have two conflicting birth locations for Dewitt S. Blackman, a 3rd great grandfather to my husband. In one instance, "Lyanes, New York" was noted in Blackman's Civil War service record, and in another document in the packet, "Seneca Co., New York" was listed.¹

Dewitt served in Company B, 47th Ohio Infantry. He was drafted and mustered in on 27 September 1864 in Toledo, Ohio for one year of service.²

Fortunately, this location discrepancy can be solved a bit more easily than my recent project with Elizabeth Kite. Historical maps to the rescue!

A quick internet search indicated that Lyons, New York is located in present-day Wayne County. Seneca County lay to the south of Wayne, in the Finger Lakes district of New York.³

Seneca County was created in 1804. The town of Lyons was formed about 1811, and was then located on the eastern edge of Ontario County.⁴ Both events happened well before Blackman's birth, about 1830.

This 1822 map shows Lyons in Ontario County, near the county's eastern border with Seneca County.⁵

In the meantime—and still before Blackman's birth—Wayne County was formed from portions of Ontario and Seneca Counties in 1823, enclosing Lyons in the process.⁶

By the time that Blackman was drafted into the 47th Ohio in 1864, Lyons had been located in Ontario and Wayne Counties successively. And due to its close proximity to Seneca County during Blackman's lifetime, it was probably easier for him to report he was from "Seneca, New York," much as one might say they are from a large city—more recognizable perhaps than their real birthplace of a nearby town or village.

The map below shows the 1829 boundaries of Seneca County georeferenced on a present-day map, with Lyons lying just outside the county.⁷

As counties were created and boundaries changed regularly during the development of our nation, our ancestors might not have moved an inch, but been located in several different counties during their lifetimes. Historical maps are invaluable in solving geographic mysteries such as where Dewitt Blackman was born, and others.

Until next time...
