I'm looking for info on the family of Richard Black and his wife Elizabeth. I was told by my grandfather that Richard had signed some treaties. Richard had the following children: Rev. Richard Black, Mary Jane (married William Rathburn and then a Mason?), Catharine (married a Smoke), and Margaret (married a George). There may be more children that I don't know of. I have no dates except that Mary Jane died in May of 1920 or 1922. Thanks.
