I suspect that there isn't really any connection, but the coincidences are remarkable:
--My parents, Raymond H. and Rose Cassell Fehring, moved to Holland Michigan in 1937 where my little sister, Linda, and I were born and lived until moving to CA in 1954.
--My maternal grandmother was a Phillips from the Boston area. She had a cousin who married Arnold Weeks and lived in Situate Mass.
It would be interesting to learn if you have any luck in clearing up some of the puzzles you have encountered in your search for better info.
