Tompkins Homestead Site 1897

I had read about a homestead site being in this area, so I have been looking for it for a couple of weekends. I found it last weekend. This is up in the mountains of Oregon.

Below is the only information I can find on the Tompkins (so far). It is from the cemetery in the closest little town, about 15 miles away from the site.

TOMPKINS, John, 13N, #107, Co D 12th Reg Kan Vol, 7 Jan 1843 ~ 23 Jan 1915, on stone with Sarah Jane North T.[wife], [s/o Reuben & Ruth Beldon T.], ALPI MIL

TOMPKINS, Sarah Jane North, 13N, #107, 4 Aug 1863 ~ 10 Oct 1905, on stone with John T. [husband], next to sister Amanda Gilman, [d/o Joseph & Savannah Bristow N.], ALPI

An update from my buddy Chris Cooper:

Company D 12th Regiment Kansas Volunteers.

Here are a few links for you brother about the 12th KS Vols

This first one is from a reunion that lists John "Thompkins" as a Private from Chehales Co. Washington.

This second one lists alot of Tompkins in the same regiment. Probably all family members, but it still lists John as a Private from Ohio City.. where ever that is.. lol.. It also says he mustered out with the Regiment in 1865 so he served 3 full years in the unit which during the Civil War was a major feat in itself.
