Sullivan, Prince and Grennan

Fellow researchers,

My Grandfather Thomas Joseph Sullivan 1899-1931 was born in Cleveland to John Walter Sullivan 1877-1929 and Catherine Grennan 1870-1916. John Walter was born in Cleveland to John Sullivan 1850-? and Mary Ann Prince 1850-? John and Mary Ann Sullivan were born in Ireland and England respectively and married in Elyria in 1873. Here is my dead end. I haven't been able to connect them to a place or parents. I went to Cleveland once in the 80s and was overwhelmed by the size of the library. Any suggestions?
