I don't know if there is any connection but my grandmother was Mary Jane Dolan born 1871. Mary was the daughter of Patrick Dolan & Catherine Cahill. Mary was said to have 3 brothers at the moment I can only find one a Michael born 1868 who married a Bridget Courtney in 1886.
I haven't found Patrick & Catherine's marraige as yet either, however from the census it seems that Patrick
was born in Galway and Catherine in Co Clare. They both claim to have been born about 1836.
bye for now
