John and Ann were married in a religious ceremony on September 29th, 1772 at St. Mark (Bolton) by Richard Longford and witnessed by William Greenhalgh & Thomas Crompton.1
Marriage/Union Notes
Several marriages of John Lomax: Ann Brook 1-Nov-1777, Bury (too late as Mary born 1774) Ann Entwistle 29-Sep-1772, Bury Ann Booth 1-Jan-1767, Bury (seems too early) Ann Rothwell 20-Feb-1765 (too early)
Therefore most probably is Entwistle, bnut could be wrong.
Mary was born on May 9th, 1774 in Bolton and her christening took place on June 12th, 1774 at Bank Street Unitarian.2
