My Great great grandfather was John Duggan of Insishbeg a small island off the west coast of Cork. He married Mary Dwyer from Colltrum and had five girls.
The girls are Johanna or Hannah 14/01/1860, Mary 22/05/1861. Catherine or Kate 25/06/1865. Ellen 22/08/1863.
Maggie 13/07/1867. Three of the girls poss may have emigrated Scotland and the USA are likely. Maggie married a Duggan of Filemuck, Ballydehob and one other sister married a Keohane of Caragh. Any information would be welcome
