I have a Mary Halkyard, b. 1830's, Oldham, Eng. She m. Joseph Chadderton. Had Sarah Chadderton who m. a "Mansley"& stayed in Oldham, & Joseph Chadderton(b, ca 1856), who m. Mary Malone & went to Fall River, MASS abt 1885-8. There perhaps were other siblings. Have no further info on my Mary, but there were other Halkyards in Fall River in the 1880's. It was a cotton mill town much, like Oldham. Without knowing more abt Mary, I have know idea how they might be related.
