Stephen, I was very excited to receive your reply to my query of several years ago. In answer to your question, I have had no further contact with Christine Harris. I checked her posting history and 2002 was the last time she posted on any GenForum board. I checked the SSDI for 2002-2007 and no Christine Harris appears.
I will try contacting you directly and see if my e-mail will go through to you. If not, perhaps you can contact me. I would very much like to explore this family with you.
