I tried to email but since your address is no longer valid will post here. If after all this time you still don`t have any info on Mortimer Sooy, I can tell you he is descended from Joost`s son Joseph (or Joost Jr.) or the J. line.The descendancy is Joost, Joost(Joseph)Jr., Noah, Samuel, Samuel, Mortimer. Mortimer`s father Samuel was my grgrgrandfather Jonathan`s brother. Samuel and Jonathan moved from Spencer Twp. Medina Ohio to Allegan Co. Mi. Another brother, Benjamin also moved to another area in Michigan. Mortimer is buried in Elmwood Cemetery in Wayland Mi. next to his father. How are you related to Mortimer? Feel free to email me. I have Mortimer and Samuel`s headstone pics if you are interested. His stone gives dates 1867-1917.
