Bill: Thank you immensely for the link to the obit. I'll request a copy of the obit from WCPL and a copy of the death cert from Williams County Record Center.
The Prettyman family and Robinson family were close although there is little documentation of this. Louis/Lewis'(b. abt 1828) father was Rev. Thomas Prettyman, whose settlement has been an archaelogical project in Williams County. George Robinson Sr. was one of the original six settlers on Prettyman's land in abt 1834.George Sr was an appraiser of Thomas Prettyman's estate in abt 1837.
