I have recently discovered that John (aka Johannes) married to Marie Hustings and John Jakob (aka Johannes Jakob) married to Louasia Franke, all of Mayville (but born in Prussia) in the mid to late 1800s, are brothers. Their parents are Matthies (aka Matthius/Matthus)Johannes Langenbach and Elisabeth Quast, of Prussia (Germany). Anyone interested may contact me at email@example.com
. It seems that there are two American branches of Langenbachs who didn't know of one another, at least in our generation. John Jakob and family moved to California in the late 1800s. It is fun to find a bunch of relatives.
