Kate, Forgive me for butting in here, but do you know that since Judith Gillespie is listed in the Social Security Death Register, you can write to them to request a copy of her original Social Security application? It would give her parents' names, as well as the address she was living at at the time of the application. Details of how to do this and what the (minimal) cost is, located on the Death Registry site. Hope that might help:) Patty
