Noel,
Joseph Johnson was christened 19July 1811 at St Mathews in Douglas to Joseph Johnston and Margaret Lace. The father was the son of Peter Johnson and Margaret Bowen.
For the family story go to Frances Coakleys site and search Bowen. Then read the Family History Society Journal 1980 and the section about 'The Heywood Connection'- the family look important.
