If you do a custom search and just put the name Creedon in, it turns up quite a few. If you don't check the esact spelling box it comes up with a few more. That's how I found my Margaret. I wouldn't have known it was she and would likely never have found her in their files, except that I recognized my g-grandfather's name. Considering that all the names that come up in a custom search are from ancestral files and are contributed that's not uncommon. There are lots of errors in those files. The regular search brings up more names sometimes, but I was looking for a contributer.This family is the closest I have found to the right time frame for Margaret, I guess I better check Colorado and she if she turns up there. Good luck with your search, if I find anything on him I'll get in touch.
