Hi, my grandfather is Harold Osmer/Osner Roche/Roach (I have found spellings to vary depending on the documents). He was born in 1908 in Erie, PA. He married my gmother, Pearl Cary and had five boys. He lived a great portion of his life in Michigan. His mother was Irene Perry, father is believed to have been Peter Roche. I am at a loss to his line at all. I can not find anything definitive past his mother Irene. There is some confusion about his father, looks as though Irene was wed at some point to either two men named Peter and Patrick, both Roche.. OR Peter and Patrick are the same man. Anyway.. Any help finding this line would be so very welcomed!
Thanks!
