I have previously been in touch with many of Josephs descendants but none of their email addresses are currently working. I am descended from Arthur Martindale who was Josephs 4th son. I will be in York April 2nd - 10th 2016 on my regular visit to the archives. If anyone is related to Joseph or his son Arthur Martindale 1870-1939 and is interested in having a get together please get in touch off list. Gillian Cattell nee Wheatley
