Sarah Bowel was recorded as resident in Shipley on the 1739 marriage entry.
Nicholas Powell and Sarah married by licence. The sureties were Nicholas himself and Edward Hards, yeoman of Ashington. Nicholas was a labourer.
There is also a 1743 marriage licence for Nicholas Powell, bachelor husbandman of Shipley and Sarah Lock spinster of Angmering, sureties - Nicholas Powell and Thomas Stringer, victualler. They married 4 Oct 1743.
And unfortunately there is another Nicholas Powell who married Sarah Gosby 16 May 1733 in Washington.
There are some burials for various Nicholas Powells - one in Shipley in 1734, one in Washington in 1760, another in Angmering in 1754.
Ann, the daughter of Nicholas & Sarah Powell was buried in Storrington in 1770.
May I ask how you arrived at Nicholas Powell and how you determined that the marriage to Sarah Ayres was the one you sought?
