I am sure they are the same person. The birth dates for your Joachim Lybbert and mine are the same. The birth place dad has is Hagenow, M-Sch, Germany. Is this the same?
Please email me direct at Maddy@a1pro.net
I can give you my phone number and my dad's number as well.
I also have Margarette Elisabeth Evars as Joachim's wife. His mother is listed as Catharina Elisabeth Wolter and father is Heinrich Detlev Luebbert. How are we doing here? I hope things line up and we connect the family.
