Hi , I think you have the same family . Milson Harris was my husband's 2x greatgrandfather. Milson did have a brother William . Milson's son William was my husband's greatgrandfather . I don't have much information on them at the moment, as I haven't long started to research this branch . Most of the info I have I've managed to get off this website ......it's a fountain of information ! If I find some more I'll let you know .
