There was already a wikitree profile for the father of John Ruggles, namely George Ruggles "Senior" (died 1616, Sudbury, Suffolk). Therefore I have attached John Ruggles as his son, and I created a new profile for the youngest son Jeffrey Ruggle (born 1585; d. 1630, Boston, Massachusetts).
What is even more exciting is that George Ruggles Senior had a son George (Junior) who was baptized at Sudbury, Suffolk, on 26 March 1581. This opens the possibility that George Ruggles Junior was the immigrant to Boston and that John and George were brothers as Anderson originally proposed (not father and son). If so, Elizabeth Bateson might have been a second wife. If there is no baptism of a George Ruggles in 1606, then the George Ruggles baptized in 1581 would likely be the immigrant. Being brothers (rather than father and son) would explain (just as well) George's connection with the inventory of John Ruggles' estate.
Source of information about 1616 will of George Ruggles Senior is from "English Origins of New England Families, Vol. III, page 615".
