Jacob R. Endly was born 08 Sep 1829 in Old Washington, Guernsey County, Ohio.  He married Eliza J. Adair ca 1856 in Ohio.  They had six children:  Maria E. Endly, Harry Clinton Endly, Lelia Margaret Endly, Catherine M. Endly, Ada M. Endly, and Bertha  Virginia Endly.  Jacob died 23 Dec 1898 in probably Mecklenberg County, Virginia.

He evidently ran a drugstore as we find this little news item:

Washington Items:
Oct 19, 1871 Thursday
Mr. James Stewart has purchased the Drug store of Jacob R. Endley, Esq.
Feb 27, 1873 Thursday

and then there’s this item, which is why I think he probably died in Mecklenburg County, Virginia.
J. R. Endly, our efficient township clerk, has decided to remove from W. [Washington Township] His destination, we believe is Mechlenburg Co, Virginia.

According to the  Census he was widowed by 1830.
