My German grandmother, Anna Elisabeth/e Berg bore my illegitimate father in Frankfurt, DE, when she was about 16 years old in 1906-7. Would she have been required to make records for her newborn (or somewhat older) in that time and place?
My father, Anna's son, was born out of wedlock (yes, simply knowing that bothered him) in Frankfurt during those years (leaning toward 1907).
Since these records SEEM unavailable, how would you advise further research to continue? Which one (or ones) might be most likely.
I'm 80 now and those living at the time did not communicate about any of this, except what appears above. I'm stuck probably because I only know the rudiments of genealogy. Please assist me if you can by providing useful/verifiable routes for this integral family research.
