Sewells of Suffolk, Harkstead

Has anyone met Elizabeth ?
Elizabeth Sewell married Joseph Barber by licence at Harkstead, Suffolk, 5 Apr 1709 (Harkstead parish register)
She was born about 1688 at Harkstead (IGI submitted record)
She was the executrix of her husband's will, proved 13 Mar 1734 (his will).
I can't find her bapt, or parents, can anyone else help please ?

Elizabeth was wid. of Joseph Sewell (Suel) when she m. Joseph Barber. Joseph Barber in fact m. two Elizabeth Sewells, both wids. I think the first Elizabeth was nee Allen, the second was nee Catt who was the wid. of the first Eliz's son James Sewell....complicated!
