A patrick WH harrigan is listed in Ancestry Com as being the son of James Harrigan and Margaret Currey. It states he was born in 1819 in Roscommon ireland. If he is the same family as mine, the parents and all the siblings came to Australia on the ship Joseph Somes arriving in Sydney on the 1/2/1852.They were listed as Horrigan on the ship but marriage and birth records kept at Tipperary town in Ireland always states they are Harrigans. They came from Ballycarron near Kilmoyler in Tipperary. The eldest son of this family is a patrick and he does not appear to have come to Australia in any records I have looked at. The Harrigans were married at Kilmoyler on the 17/1/1824.I have been unable to find baptism records for the first 3 children - Patrick, William and John inTipperary, so they may have been wandering around.It states on Margaret (Currey) Harrigan's death certificate (dated 29/11/1884) that Patrick was still alive and aged 64 (so that is about right). My mother was a Harrigan - descendant from John and that is my connection.
So we may be distant cousins. It would be nice to unearth a baptism record for your Patrick.
Patrick is also listed in the 1880 USA Federal Census as being at eau galle dunn, wisconsin.
