I will get this right yet as to fully explaining the Boyce-Walker-Greenhalgh-Holsworth-Whitehead, ETC. connections! In last message I referred to James Greenhalgh and Mary Ann Boyce: they had three children: Robert Greenhalgh (1819-1887) married to Emily Harwood with their three children Ernest, Emily and Edith; James Holsworth Greenhalgh, died September 1870; Mary Sarah Greenhalgh (1824-1904, my third great-grandmother)who married Edward Hawxby Walker (1814-1892) in 1844 at St. Pancras Church in London, England. Beatrice Agnes Whitehead married their son James Greenhalgh Walker in 1878- his second marriage was to Elizabeth Atkinson in 1913.
Again, any additional info, please post or send me a message. Thanks from Nora in Alberta, Canada
