Its a bit of a long shot but I have family links with Mulholland's, Hardie's and Marne's (Marron) in Ahoghill and later with the Blaney's in Scotland.
My Grandmother, Annie Blaney(1889-1956) married Patrick Mulholland(1890-1945) in 1913 in Glasgow. Annie's Father (Hugh Blaney born 1862?) married Bridget Rice (b1863?) in 1885 in Shettleston (nr Glasgow). I think Hugh was born in Ireland and his father was called John.
If any of this is relevant let me know.
Also, if anyone is interested in the Mulholland's, Hardie's and Marron links with Ahoghill and Glasgow please let me know as well (I have some info but I need all the help I can get!)
