I am looking for some members of at least two Bozer families originally from Noble County IN or Lagrange County IN who ended up in Isabella County in the 1870s or so. One family is that of Truman (born 1847 or so) and his wife Sarah of like age and that of his son Charles, born about 1878. Charles had at least two sons Carl J. and Bruce W. and a daughter Dorris born about 1905, according to the 1910 Census.
Truman had a daugter Effie, born about 1878, who was living with him and his wife as late as 1910 (at least!) in Deerfield Township, as was his son. Deerfield Township -- I saw the map -- looks very rural and I suspect that they lived on a farm.
The 1900 Census gives some birthyears and months for the family members: Truman, Jul 1844; Sarah (maiden name unknown) Jun 1847, Mary E., Jun 1889; Charles B., Oct 1877; Anna J., May 1873.
I suspect that Truman Bozer married in Michigan.
