This pedigree:
https://www.geni.com/people/John-Wis...00024007238871
shows John Wise dying January 1563/4. His eldest son, Thomas, is eighteen years and 4 months. His second son, John apparently married Emmet Vavasour. John junior presumably was 17 or younger at the time.
Sidenham is in the parish of Marystowe - roughly equidistant from Launceston and Tavistock. IE, west of Dartmoor.
"My" John Wise is of Totnes, ie east of Dartmoor. He is shown in modern pedigrees as son of John d Jan 1563/4.
Unfortunately, his wife predeceases him and is not named in the baptisms of their children. However, he is a grandfather when he dies in 1602, and his daughter Ellnor married in 1574.
Willmett Wyffe of Mr John Wysse was buried 8 March 1573/4.
"My" John has lands in Dawlish and Dittisham - both near Totnes.
Surely, he cannot be the son of John d 1563/4, though he might be a cousin.
And has anyone found Emmet as a variant of Wilmott?
