I think that you are right Mike. I haven't been looking at Sansbury family since Spring and just got back to the message board. Looking in the file I think that John Sansbury's parents were Richard Sansbury and Margaret Gawn but have no proof other than an IGI record at present so need corroboration. Strange that none of his children were called Richard. By the way I have a copy of John and Ann's marriage register entry from the General Registry of the Isle of Man.
My family file also has Richards parents as Richard Sansbury and Elinor Quirk but only tenuous link, IGI again, and not in Rushen records but Patrick.
Glad that Kay has got her Johns sorted. Too many Sansbury's on the IOM!
