My info comes mainly from the Heidelberg book published in 1982. Some of is from info my g-gf wrote down. If you're not familiar with the H'berg book, there is info about it in some of the other posts at this forum.
It would be most helpful if you could post your H'berg lineage at this forum like I did. I'm sure there are many who would be excited to see your info. It could help someone find that missing link they've been searching for.
It's always exciting to hear from a cousin, no matter how distant.
