Hi Ellen!
Thanks for posting here.
In addition to your question here about Edwin, you might also want to send a private message to the profile manager David McDougle, using the "Send Private Message" link that's next to his name on the profile.
Your post here is to the public G2G forum, where David might not notice it, making it less likely to get a response. A private message would be sent through WikiTree directly to David's email making him much more likely to see it and perhaps respond.
Thanks!
