Looking for any information pertaining to my maternal great-great-grandmother JULIA (COLLINS) DONOVAN.

She married William Donovan, from Dunmanway. Among their children were:

Hannah (b. 1867)
Mary Ellen (b. 1878)
Eliza (b. 1864)

When she got to Boston, Hannah married a man named Cornelius J. O'Sullivan, also born in Dunmanway: Cornelius's parents were CORNELIUS and JANE (GORMAN) O'SULLIVAN/SULLIVAN, married on Feb. 2, 1861 in Dunmanway, Cork, Ireland.

Among their children were:

ANNE (9/16/1865 - )
MICHAEL (8/12/1867 - )
CORNELIOUS J. (11/5/1869 - )
JANE (12/3/1871 - )

Any help is most appreciated!

Thanks,
TSL
