Neither.

1. There is a grave monument, for Catherine Goode. She never even married a Robert Bevill. Catherine only married Sir Robert Hampson and Sir John Rotheram. It was her daughter, Elizabeth Hampson, who married Sir Robert Bevill, Sir Gilbert Wakering, and Sir John Hewit.

2. William Bevill was baptized 6 Feb 1604. This would make him the son of Robert and Mary. This William, however, died in 1638, his will being proved on 10 Mar 1638. This is around the same time that William Buell is landing in New England.

So...William Bevill and William Buell are not the same person. It is unknown who both William Buell's parents are.
