I am searching for the family of my great grandfather, William Riley Sullivan, born abt. December 18, 1842 in Indiana, wife's name in Missouri was Mary L (or Eliza) Lane. His father's name is reported to be Robert, but his mother's name is unknown. I have found a B.R. Sullivan in Indiana census for 1860 that Lists a William R as a son. Can anyone help me? We have been looking since about 1963 to find my great grandfather's famiy.
