Lucky she!
No problem with accepting advice and the rest here. Thanks for your concern.
Through Rootschat I now have much more than an outline; have found a cousin (she me, actually) and have been able to give infos. to my half-sister here in France. She, incidentally, with her very first use of a computer, replied to my original request through Rootschat.
It's been a big step in family history.
Best,
