I still think same family. Ages pretty consistent for John and Catherine, except for possible Catherine in 1920 which may not be her. I think possibly Catherine and Michael were separated in 1920 but would love it if someone could find them. Also would love to find John White's death abt 1901, as per 1910 census. And Catherine's remarriage to Michael Hennessy abt 1902.
