My GrtGrt Grandmother was Catherine Abrams (spelling ??). She was born approx. 1851 in NY. Catherine was the daughter of Isaac (who was born in Ireland). Catherine married Robert McCollough and lived in NYC (Manhattan) at the time of the 1880 census. Catherine and Robert had 3 children (as of 1880), Rose Ellen, William Robert and Catherine McCollough.
If anyone has any information on Catherine and her family please post a reply or contact me.
