German Roots Brick Wall Help Needed

Question

I've been stuck on Katharine Sauer in my family tree for quite a while. I haven't been able to even find her approximate or exact date of birth. I know her name almost only because of her children's death records. I know she was born in Germany from those same records. If anyone would be willing to take a quick stab at finding some information on her DOB or parents, I would greatly appreciate it. Sometimes one person looking at something too long is counterproductive. :)

Comments

There is a small mistake in the profile name.

It must be Rothenberger not Rothenbeger.

The family Rothenberger is still located all over Baden-Württemberg.

Thank you for pointing that out! It was definitely a typo. I have her husband's LNAB correct with the r.

Answer 1

Katharine, I don't know if this helps but I found this Katharine Sauer who was born in Germany.  

Sept.5th 1892 in Bonne, North Riine -Westphalia, Germany

Died  : 01-21-1946

Was married to a Wilhelm Rommerskirchen.  I found the infor on family search under her name.

Answer 2

look for different spellings, Catherine, Katerina, and Katherine as the middle name. 

Check these two web sites,

Answer 3

On Familysearch her Birthplace is listed as "Stuttgart, Wittenburg, Germany". This is in my opinion (as a German) wrongfully transcribed. The real word should be Würtemberg. There is no Stuttgart other than the one in Baden-Würtemberg known to Mayersgaz.

To search further I would suggest looking in the Illinois Census records of cook county. or try to dig up the marriage or death records.
