Thank you for your lengthy and detailed reply. I appreciate and thank you for taking the time to type it.
I am an amature, there is word of mouth family history, and there is paperwork tracking history. For me they are not matching up very much, i have reached many dead ends or conflicts in information i have collected.
My initial post was "casting a net" type post. I will put into words later what specific issues iam having, as i am still organizing the info i have now.
It seems the area of denmark my dinnsen family was from was part of denmark, the conquered by germany during the schleswig-holstien wars. So my family data uses danish names for places that were switched to german names.
Thank you for the links. I do know there were 4 generations of "Broders" so that is creating some challenges in addition to 3 generations of "Carstens"
