I'm pretty sure that we're looking at the same Alexander Fischer and the same booklet. I got the booklet from my father who is apparently on somebody's mailing list. I didn't find a date on the booklet, but it lists my son who was born in 1977 (listed as 1947), but not the boys born in 1980 or 1982.
I don't have any information beyond what is in the booklet for Alexander Fischer or his son Jacob Fischer. You mentioned that Alexander had 9 children; my booklet lists 3 more by a second wife.
I'll try to remember to forward anything I learn about the Fischers. Which of Alexander's children are you interested in?
