I have found Richard Arnold's will, and the is no mention of a daughter, Rebecca. The will was written and proved in 1720, so Rebecca would still have been living since her child Andrew, Jr. was born in 1731. She had died before 1745, because her husband remarried to Jane Antrum in that year. But why would she not have been named i her father's will? The will mentions sons, Anthony, William, Thomas Joseph, and Richard. Daughters Sarah, Grace, and Elizabeth.
