Hi Patricia,
When I learned about the church records kept for my great, great grandparents (St. Joseph's church in St. Louis) I noted the Feld/Brand marriage of 1851 and wondered how the families were related. Four of us have documented our Feld family histories to the early-to-mid 1800s in Emsland and have yet to discover common ancestry there. It's my guess that we'll have to piece together family relationships back to the 1750s to find the link. In the 1790s our surname was spelled Veld in one point.
