I received this information from JoAnn Dobbins via Email. If anyone knows any more information please contact me.
She writes, I live not too far from the area that the Lapps lived and the Mennonite cemetery where Martin and Samuel are buried. Originally, according to a book I found on the history of the Mennonite Church, Martin and Samuel lived in New York. But they did migrate here from Canada. Abraham is buried in the Lapp Cemetery in Willoughby Township, Welland County, Ontario, along with some children. His wife's name was Elizabeth. Martin and Samuel also had a brother Isaac. Both Martin and Samuel helped form the Mennonite church in Lancaster Township here. Martin is listed as the first minister and Samuel as the Deacon (until the day he died) Martin later migrated to Missouri where he became a bishop in the church. He eventually returned to this area. I found this information in a book at the State Historical Library in Madison, Wisconsin. I do not know at what point my branch of the family broke away from the Mennonite church, but I do know that My GGF, William Henry, was not a member of that congregation (He was a life long member of the M.E. church.) His wife died at age 29 years and was originally buried in the Old Mennonite Cemetery, but was later moved to the Dakota Cemetery. I have never been able to find out why she was moved. They are both buried there, along with Martin S and Sarah.
