Dear Ingrid;
I wrote to you awhile back about my Heyne- Schweers ancestors. They may be related to this couple but were several generations older. Possibly the ones you found are descendants of these earlier branches. Here is what I have. Do the hometowns of Lintel, Hude have any connection to Brake or Hurrel?
Johann Harm Haine (Heyne) was born on April 28, 1759 in Lintel. He married Gesche Margrethe Schweers who was born on October 01, 1762 in Hude Lintel. They married in 1799 and both died in Lintel before the births of the people you listed. He on December 07, 1829 and she on February 25, 1827.
Please let me know if you think there are any connections.
Thanks -- Hank
