I didn't have ancestry when I posted originally. I have found several things today.
Last child born to Daniel and Eliza was age 5 in Dec 1857 born in Ind. and Daniel married Ruth Buckingham 15 Jan 1857 in Fillmore Co. MN (https://familysearch.org/pal:/MM9.1.1/FD82-ZVW). So I'd say that Daniel is likely buried there, found him with Ruth in the 1860 census there too. Eliza, well she must of passed between 1852 and 1856, either in Adams/Jay county Indiana or in MN I would guess to start looking. Hopefully, I can find some good burial records to look through on-line.
I would imagine that the kids would of buried Daniel with Eliza if they had their choice. I haven't seen where he had any children with Ruth. She might of been a widow herself. Who knows until we find something more.
