hello i believe your Robert John Pershing Berens is the brother of my grandmother, Catherine Berens Anderson. My aunt is the only one of Catherine's five daughters still living (she is #4; my mother, #3, passed away)
I have just started looking up the Berens. It looks like the Nicholas married to Jennie Thompson (my great grandmother) had a son Nicholas and also his father was a Nicholas. Is that right?
I saw a message from someone named Penny and it looks like she is also a relative, and I have emailed her too.
This is very interesting and so very fortunate that there seems to be so much information on my grandmother's (your great aunt's?) family.
I would welcome a message from you: i email@example.com
