Hi Eileen, From 'Lionel Udall & Abigail Bill, Stonington, Connecticut, Progenitors of one Udall/Udell America,' a Review by C. Melvin Bliven. [I have his contact data.]
From Page 3 of 23 written by a great grandson, John Udell,3...Lionel Udall was an innkeeper and physician of Exeter, England, had a wife Anne and a young son Lionel; he left hurriedly, furtively, for America and arrived in Stonington; after learning of the death of his wife and child, he was a widower and married Abigail2 Bill in 1727 who is also without estabished antecedents.The accuracy of these statements is not known, is dependent on family lore.
From Page 9 of 23 Lionel Udall is said, by Champlin,26 [I have this source] to have been a 'practising physician...in the first half of the eighteenth century...a man of considerable prominence...Dr. Lionael Udall left an account book containing listings of his patients from 1750 to 1767;
From Page 10 of 23 Abigail Bill Udall has a gravestone in Queechee Cemetery, Windsor County, Vermont, graven 'In memory of Mrs. Abigail Udall Consort of the late Lional Udall who died May 1780 aged (blank)."
