I have a pedigree of about 350 Irbys in England (and later Australian branches) from about 1100 to the present day, including the continuous line of oldest males over the last 900 years. I will perhaps key this into a GEDCOM file if ever I get the time(!!) and post it. What might spur me on is if anyone can demonstrate a link between British and American Irbys. For example, has anyone traced the antecedents of Dr William Irby, Charles City County, 1625-1680?
