Hi Liz....
I found a will for James H. Tiffany
https://familysearch.org/pal:/MM9.3.1/TH-1942-24599-42157-7?.... In it he references his sister Almira and a nephew named George Norton. He also indicates that he's leaving property to the nephew if he stays with "his family" until the nephew is 21. There is an Almera Tiffany in Bath, Steuben, NY in 1840.
I also found information in the Landmarks of Steuben Co. indicating that a Dr. Samuel Le Gro married an Almira Tiffany as his second wife.
https://books.google.com/books?id=NvM1AQAAMAAJ&pg=RA1-PA... Interestingly, Dr. Le Gro and Almira are buried in Grove Cemetery in Bath, NY along with James H. Tiffany and Willis N. (and his family). I expect Almira, James H. and Willis N. are all the same family group.
Will keep digging.
Sheila :-)
