Jonas has been useful in my line. Even though the family of Jonas changed their name from Broadley to Bradley in the 1750s, leaving their brothers as Broadley, the name of Jonas helped me follow the Bradley line forward through all the other unrelated Bradleys. It helped me get back from John Broadley of Church, Lancs 1660-1733 (sons Abraham, Jonas, John) to his father Abraham of Darwen, Lancs (sons Abraham, Jonas, John). Even before the Y-DNA project which took us back to Halifax in Yorkshire, George Redmonds' book Christian names in local and family history, told me that Jonas was a highly unusual name which came from Halifax. I had checked the Blackburn registers for several years either side of 1654 and found no other Jonas and only half a dozen Abrahams. Having got back to Warley, I found Abraham 1632 son of Jonas and Jonas, 1588 son of Robert. Unfortunately, he was the first Jonas. I am now faced with 3 Roberts of Northowram all born about the same time in the 1560s. I am very grateful to Jonas! cb
