Thanks for taking the time to respond to my post. I appreciate it. I already have both the 1930 and 1940 census records and have tried searching in earlier censuses for Kathleen based on the limited info in those later censuses but no luck yet. I am also familiar with requesting the SSN application - I'm just not sure I want to spend $27 yet so I was looking for other ways (like hopefully an obituary or something similar). Thanks again for your help.
