This is wrong it isn't the Osborn family but the Wilmot family who married into the Horne family.
The Wilmot was Peter and he was the Chief of the tribe at the Indian Reserve Trust Pictou co. Peter had a son Charles who had a lot to do with them.
Peter is the son of John Wilmot and Mary. He married Isabella Innes d/o Daniel Innes b 1869 and Margaret b 1870 in Scotland.
I guess his other kids didn't do that much they were William S.M b 1879, Margaret 1881 and Frederick AL b Oct 11, 1877 who is the father of Catherine Florence Wilmot b 1903 and married Ambrose Leo Horne and her mother was Maude Osborne.
There is a lot of info on line about this tribe and Chief Philip. A picture of him and another of his son and wife.
