Their US purchase family bible has three different spellings in it...
Thomas Coggins/Cogan/Cogans was born 8 Mar 1830 he married Ellen Finnerty/Fenaghty [b Mar 1826] in 1856 in Ireland. They left and came to the US - he in 1865 and she in 1867.
They had children all born in Ireland - Andrew [b1856], Patrick [b1857], Mary [b1860], Martin [b1863] and Timothy[bMay 1865 -perhaps Tadg?] who all came to the US [Massachusetts]. Timothy is my G Grandfather.
Thomas's mother also came - Mary [Feeney][b1787], not sure what happened to his father - Andrew [b abt 1796].
Ellen Finnerty/Fenaghty/Finaghty parents were Timothy and Nelly/Nellie Boland.
I have looked through the Griffiths Valuation and see most names in Sligo...perhaps Dromore West???
Sure would like more info or to narrow it down in Ireland...trying to make plans to head there in 2013!
