I am researching my mother's side of the family which includes members the above families who were located at one time at Ohsweken.
My grandfather was Saul Johns (b1913). His parents were Isaac John and Beatrice "Hattie" Sherry. Hattie's parents were Solomon Sherry and Lucy Brant. My grandfather was one of about 7 or 8 children. From what I have been able to determine, Isaac & Hattie left the reservation sometime in the 1920s (4 children, including my grandfather, were born on the reservation). From some of the history I have been able to obtain, there are Powless and Maracle names that are attached to this John(s) family.
If anyone is related to the above families and would like to share information, I would love to hear from you.
