Hello Ell, sorry about the delay, but "things"happen, anyway, I have downloaded the card info, clarified it and printed it A4 size.
Looks like Helene was "sent home" because she was senilie and I reckon the daughter is Lena Heyer.
Thanks also for the freedom of information info.
I think you are right, the Helene Wilhelmine Burg does not sound like the right one, but Arlene Burg might be someone to check out. I'll see if I can find her.
Cheerio, Dee
