Hi Antonia, and welcome to RootsChat

I have just sent the original poster a Personal Message advising him for your post. I hope you hear from him soon.
I see that there are others who also posted in 2014 and 2018. If you reply twice more to this topic, just a smiley in the text field will be fine, you will activate your Personal Message facility and will be able to send and reply to private messages. You could then try to make direct contact with those members to further your research.

Personal Messages (PM)https://www.rootschat.com/help/pms.phpIf you have any questions you are welcome to ask me by PM or post your question on the topic and I'll reply.
Best wishes,
Spades
