Hello Carol, Thanks for your help. :) I do have a copy of Rosetta's death certificate; just the simple return of a death in the City of Philadelphia. It lists her as being born in Ireland, but nothing about the parents. I haven't checked Annie O'Toole Brogan's death certificate, but know from census records that she died sometime after 1930. William and Rosetta O'Toole Whitehead and some of their children are buried in New Cathedral, which I found out is part of the Archdiocese of Philadelphia. I read online in some forums that they charge $15 per record, but unless their policy has changed recently, they do a lot profile for free, so they'll tell me who has been buried with William, Rosetta, and some of the children. I also found out that there's an organization called the Philadelphia Archdiocesan Historical Research Center (PAHRC) that I can pay to look up baptismal and marriage records, so as soon as I can afford it, that's what I'll do. :) Hopefully through the combination of all of those records, I'll be able to find at least the county of origin for the O'Tooles and pursue that further. I also need to trace William Whitehead's family, but for now, I'm just taking it one step at a time. :) Don't want too much on my plate at one time.
Thank you and your help is very much appreciated. :)
