1820. She is married to John Evans b1798, a tailor. The ages of the children indicate a marriage before 1821. There is an IGI record at Coedana (within a mile of Llandrygan) of John Evans on 23 May 1820 marrying Jane Prichard.
1820 There is the birth given in IGI on 15 Oct 1820 at Coedana of Owen Evans to this couple. John Evans to them on 03 April 1825 at Llandrygarn, Anglesey. William Evans on 6 April 1828 at Llandrygarn, Anglesey. There is a fit with the later census information, and I would be confident we have the right marriage.
