Hi, I am also an Adshead, I have been researching my father's side back up to 6 generations and have found that most of them originated from India from one english Ancestor in the 1800's. And that the Adshead's you mentioned are currently in Australia, half of them is in my family tree. I have come to a dead end on the english ancestor - Captain James Adshead who married Ann Coats in 31.12.1814 in Madras, India. I cannot find his birthplace in UK
