The Merren surname comes to me via Evelyn Hauer. Her great-great-grandmother was:
- Anna Gertrud Merren, wife of Wilhelm Wolfschläger. Anna and Wilhelm would have been born about 1780, give or take, as their son Johann Peter was 25 years old at the time of his marriage in 1829. The image above is a detail from that record. The marriage took place in Helden, Westfalen. I'm not sure I'm correct in my interpretation that Merren is both a place name in line 2 and Anna's surname in line 3.
