Hi Rick,
It seems Constance may not have charted the Quaker line, which is surprising given their notoriety.
As I had no access to Constance's charts I was obliged to isolate the various CALLOW lines in order to find which one I belonged to. Eventually I found that I linked to the Simon CALLOW (Balldromma) family, which is not covered in the "History of Kirk Maughold".
I would welcome the opportunity to get a copy of the charts, if possible, to see how my efforts stack up against those of William & Constance.
My direct email address is available at my website
