Just to update everybody, your information was so helpful, I contacted the Archdiocese of Baltimore and while they had no information, Theresa had researched her own Irish kinsmen. She directed me to the Baltimore Irish Railroad Workers Museum. They did a search and directed me back to the Tithe Applotment Book and reinforced the truly limited number of Crumlish's in Ireland in 1800. Further poking took me to rootsireland.ie where I was directed to Brian in Derry Genealogy who practically wrote me a dissertation on Irish Crumlish history...all of which was new to me.
Without your direction, I would have gotten nowhere.
Thanks to all of you.
