I'm not related to this family.. But there were NO hostile Indians in Indiana in 1910. In fact,there weren't any hostile Indians in the USA then.Most had been removed to reservations and were living under treaties devised by the Dept. of Interior, Bureau of Indian Affairs.
I could not find any information on this family through census records for 1920.I did see they immigrated to US in 1894. It also stated that Louisa had 2 living children.Do you know the other ones name besides Margaret?It's as though they disappeared...did they move to another state after 1910?I know there was a terrible epidemic of the Spanish Flu in Indiana in 1918....could possibly wiped out the whole family.
