I would be most interested in what further information you have about the Iggo family.
My e-mail address is noSPAMjgmiller at pt dot LUnoSPAM
without the noSPAM at the front and end obviously. ;)
I understand that the Iggo family in Newcastle-Upon-Tyne originated from Scotland, and perhaps are descended from Danish immigrants in the 8-9th centuries.
Thanks for your assistance.
