Wife of Ruel Blakslee/Blaksley/Blakeslee. They were the parents of:

Maver Blakslee 1841 - 1915
Oscar B. Blakslee 1842 - 1928
Oliver Blakslee 1847 - 1913
Chauncey R. Blakslee 1851 - 1901
Milton Blakslee
Sarah M. Blakslee 1852 - 1859
Charles B. "Foreman" Blakslee 1854 - 1929
James B. Blakslee 1856 -
Sarah A. Blakslee 1863 - (John Smith)
Ella Blakslee 1865 - (Jacob Hulse and John L. Somers)

1870 Censues shows two S. A. Blakslee. I believe the second one should have said Ella Blakslee/Blakeslee. Some of the years of birth on census records doesn't quite match up with what I found from death records and burial places.

Note: I have looked and looked for more information on him and his wife and have not found where they are buried. I have tried different spellings of first and last name and have had no luck either on him or his wife Anna. I believe they both must have passed away after the 1880 census because I can nothing for them after that. I make this memorial anyway to be able to connect the children that I have found so far.
