2. In an email from Harry Nash (14 Oct 2002), he gives his thoughts on Elizabeth’s Certificate of Death which he was kind enough to send me a copy. Harry writes the following:
...“Place of Birth - Bransmith. No such place. More than likely Brancepeth, County Durham. John Wakenshaw was the informant and he was from Hartleypool, which was in County Durham and he would have pronounced the place name as the locals would have, which would be Branspeth. The ear of the recorder hearing this may well hear Bransmith.
...Date of Birth - February 29th 1832. Well, maybe. However, Elizabeth has had many birthdays. 1844, 1846, 1841 and 1832. I am not sure when she may have been born. In the 1900 census of La Salle county Illinois, it states she had had 11 children of which 4 where living. Ann, Elizabeth, Ellen and ?. The Gaffeys arrived in the U.S.A in 1870 and at least two children were born in America. That leaves at most nine to be born prior to 1870. One birth a year maximum would mean a marriage about 1856 at age 24 (1832 birth date).
...Parent's names - Father's name Culbert. Well, my grandfather's name was Culbert and my middle name is Culbert. However, the LDS IGI has a marriage between a Cuthbert Wolf and Ellen (Eleanor) Hardy of Gateshead, County Durham (Newcastle is on the north side of the Tyne and Gateshead on the south). So, I suspect Culbert may be a corruption of Cuthbert.”
