Wow, another Irwin appears. There is also a strange story appearing: Kevin Statham reckons William's wife was born Greenup. And their marriage certificate certainly claims she was a spinster at the time, but leaves the surname blank. Whereas William's son Edwin syas his mother was a widow called Dorothy Greenup when she wed his dad, and that she was born a Birkett. And their eldest son John started off as John Irwin (as you would expect), but changed his name to Greenup at one point, and then back to irwin ten years later. Many explanations spring to mind, none totally satisfactory. But when "William Irwin" the biopic comes out on general release, expect some steamy story lines.
    So Kevin Statham, if you come back here, can your genealogical researches throw any light on that?
I am very gratified by the huge number of descendants Irwin has, CD sales are going to be spectacular.
