This is a family tree for the Nicholls-Ryan-McIntyre-Jackson families. It includes well researched information in many places, best guesses in others. Mostly the data are reliable, having been carefully traced through a wide variety of sources. It's not intended to be the definitive description of the family genealogy, but a guide to the many and varied ancestors responsible for me being here and doing this. I take no responsibility for the mis-deeds of my ancestors, particularly not Sir John Jackson, Bt.! You can find me here.
