Years later, I finally purchased the 1990 Threlfall book. It's horribly disappointing re its use (or lack thereof) of source citations. It says nothing about Henry's ancestry other than:
"HENRY SCOTT (Edmund, George) was baptized on 1 November 1560 at Bradfield, Saint George, Suffolk, England." (Page 411)
Threlfall offers NO source for the baptism, his father's name or his grandfather's name.
Ugh, this book is so frustratingly organized. There *is* a page for Edmund (p 418) and then for George (p 423). But they are not grouped together. And as you see, the father comes pages *after* the son and the grandfather after the father. And there are other people (married-ins) in between. There does seem to be evidence that this is a family unit if one is willing to trust Threlfall's uncited claims. About George, he says:
"GEORGE SCOTT of Bradfield Saint George was probably born about 1495, presumably in Bradfield. He was perhaps a grandson of Adam Scott of Bradfield who died testate in March 1474/5, leaving his estate to George Scott and Benedict Freg---, probably a son and married daughter.
"Robert Scott of Bradfield who died testate in March 1558/9 was probably a brother to George. Robert in his will mentioned a brother Thomas Scott, wife Idonye, 4 children: George, James, Joan, Agnes, and George Hunt, his brother-in-law
"George Scott died in late 1547 leaving a wife named Margaret, theee sons and an unmarried daughter. An abstract of his will follows:"
(Will mentions wife Margaret, son Edmund, son George, dau Isabel, son Nicholas; his mother; son Nicholas' children who are under 21; each godchild; every servant taking wages; to every servant not taking wages; William Wyatt:Thomas Swanton; my master Sir Thomas Jermyn to be supervisor. Witnesses Richard ----, priest, James Chapman and Robert Scott. )
