I have been researching this family as I relate to Rev William Gulston of Wymondham. I have a document that names said William's brothers. The lines from the brothers appear to link to the Anthony Gulston that is mentioned in some early posts on here. Rev William had many children including Theodore Gulston MD. Having read Theodore and his wife's wills he indicates a connection to Anthony and Anthony's son Theodore without specifics. The earlier document illustrates the connections if the lines of William's brothers Henry and Humphrey are followed forwards.
Hope this is of use to you who are interested. Contact me for more details.
