What would you like to know? As far as we can tell, Jacob is the son of Edward Barney and Christian/Isbell/Isabell/Isobel ROOLE of Bradenham, Buckinghamshire, England. There are several researchers that believe they have found a full tree spanning back to the 13th century, but other researchers aren't quite so convinced.
Jacob was born on 21 May 1601 in Bradenham and came over from England in the early 1630's with his first wife Anna and their child Jacob, Jr. He was a Puritan by religion and a tailor by trade, but he was deeply involved in the community and had other duties.
After his first wife passed, he married again in Salem, Massachusetts to Elizabeth Anna CATESBY, his second wife. He had at least four additional children: Hannah CROMWELL, Sarah GROVER, John and Thomas.
On 14 May 1634 he was admitted to the Massachusetts Bay Colony as a Freeman. He was active in the Boston community and served on the first grand jury in North America. Thanks to Sidney Perley's History of Salem Massachusetts, we have his signature (page 283).
