Have yet to find a date when this photo was taken. Assume it was about the time that Ann might have been finishing high school. Ann was born in 1906 and Marion in 1908, so assume this might have been taken some time around 1923.
Neil McArthur and Johanna Murrary were the parents to my Grandmother Ann Elizabeth McArthur. Ann did not spend as much time on the genealogy for the McArthur's as she did for her husband's Grant family heritage. The Grants were trying to get reparation and "Le Pay" from the Bureau of Indian Affairs via tribal treaties.
I think it will be harder to find genealogy information on this portion of the family.
