Sorry for the late reply (haven't checked the GenForum Boards since '99...at the time they weren't producing any "hits")
One of my Margaret's (Margaret M. FUREY) was b. 17 Mar 1831 Pleasant Gap, Pennsylvania. - d. 15 Jul 1911 Spokane Washington. I have one husband for her: Joseph M. McKIBBEN. In 1850, she was 18 and living with her sister, Rachel FUREY_LATIMER.
The other Margaret FUREY wasn't born until 1868. Sorry I can't help.
