Priestman married Rachel Bragg (1791–1854) in 1814. The columnist "W. W. W." (
Old Newcastle Tradesmen) stated that Priestman was known as the "handsome Quaker". The couple had six daughters and three sons. • Their daughter Lucy married
John Bright in 1839, and died in 1841; she was mother of
Helen Priestman Bright, born in 1840. Of the sons, David, born 1824, died young in 1825. • Hadwen Bragg Priestman (1820–1884) married in 1860 Emily Jane Slagg.
Jonathan Priestman II Priestman's engagement to Anna Deborah Richardson, eldest sister of
Elizabeth Spence Watson who married his close friend
Robert Spence Watson, was broken off in 1850. Their father was Edward Richardson (1806–1863), leather manufacturer, the second son of Isaac Richardson, eldest son of John Richardson of Lowlights and brother of John Priestman I's partner William Richardson. They were therefore close relations, unlike Priestman's wife Lucy Ann Richardson. Her family had originally been in
Kingston-upon-Hull, moving to Whitby and then
Sunderland. Her family home was in
Benfieldside. The couple had two sons and three daughters. The affairs and failure of the Northumberland & Durham District Bank were of concern to the younger Jonathan Priestman, since his father-in-law Jonathan Richardson had been its original manager in 1836, and then a director. The impact of the failure on the local Quaker community was serious: the Newcastle Meeting investigated the conduct of six Friends closely connected with the bank, Jonathan Richardson was singled out for blame in the press, and his children, apart from Lucy Ann, resigned from the Meeting. Her husband Jonathan Priestman II suffered financially, having to leave his house at
Shotley Bridge and move with his family back to the family home in
Benwell. In 1864, Priestman was appointed joint managing director of the newly-formed
Consett Iron Works company, with
David Dale. Subsequently, he was a coalowner. ==Notes==
