I have Kaldenbachs from Washington DC area, Prince George's Co., Maryland, and connected to Pennsylvania. I believe these families are connected. Matthais Kaldenbach(b abt. 1821) married 1-Elizabeth McCubbin, 2-Ann Eliza Hook, 3-Mary Jane Hyde. all in PG County, MD. There is a Theresa Cecilia Kaldenbach(b. 1825) who was married in PG County, MD to William Thomas Hyde, believed to be a brother to the above Mary Jane. I'm trying to determine if Matthais, Theresa and Andrew were siblings, and if their parents were Andrew Kaldenbach & Susanna Matilda Young of Berks Co. PA.
