I am looking for information about Mary Goff, originally from Stamullen Parish County Meath, Ireland. She married Laurence Farrelly (who changed the spelling to Farley in America). She died in Stephenson County, Illinois; and, Laurence (also spelled Lawrence in some records) Farley and his family (four children in all) moved to Union County in Dakota Territory (now SD) in 1870.

Her children were born between 1836 to 1853. I have no birth or death dates and no info on her Irish parents.
