I have several references to William Bursey "citizen and free mason of London" who died in 1686, including his will which names 8 grandchildren. He was actually a coachmaker with premises in Cow Lane, London but had become a freeman of the City of London through the Mason's Company because the Coachmakers were not incorporated as a Livery Company until 1677. He sold a cottage near Harpenden in 1669 and the information I have gathered comes from my attempts to trace details of his other property in Hertfordshire. The Society of Genealogists in London have a "History of the Bursey family" by Peter Bursey (1982)- typed and bound into volume 74 of their "Family History" series. The use of the variant "Bussey" is referred to and the son of the above (also William) actually witnessed a document in 1680 as "William Bussey"
