I too, have tried to fit the Gangloff lineage together and offer another Gangloff to the list. Johannes and Christina came from Wurtemberg in 1832 and are in Mahoning County in the 1850 census. My g grandfather John was born in Columbiana Ohio in 1839 and has two siblings born in 1832 and 1836 unknown where. Perhaps this may be part of the missing link?? I have been unable to find any connection that confirms this, other than family tales that talk of missing brothers similar to your stories.. Johannes & Christina are listed as being born in Hochdorf, Vailhagen in 1800 and 1802 respectively, however I cannot confirm this information. Am still searching and looking for any info that may help all of us determine what and who goes with whom. Also I have an obit for Phillip in Wyandotte Cty indicating he was from Alsace, but cannot connect him to my lineage. If any of this helps, feel free to reply.
