I just came across your post and was talking to my grandmother about my grandfather who is from Samoa.
He had a sister who married in the Stowers family. He also had a sister named lelia.
My grandmother said my great grandfather was a chief and a police man. He died from influenza when my grandfather was young. One of his brothers or sisters ran a taxi service as well. His sister Lelia help raise him.
His name was Isaia falo . Maybe there is some relation to you granny.
