Barbara,
I'm looking for more on James M. and Lovisa Sherwood Tillman. He had a brother Peter M, I believe. I found the in 1850,1860, and 1870. Can't find them in 1880 and after that time. They were still in Oakland, Susquehanna, PA in 1872 and maybe as late as 1878 as James was the administrator for his brother's estate. I have info. on the parents of Lovisa, but don't know much about the Tillmans.
