Having spent several years researching the Lickiss family across the entire UK, Australia, Papua New Guinea, USA and Canada. I have yet to find a single Lickiss anywhere in the world who is not a descendent of John Lickiss from Sessay in Yorkshire in the early 1600 and Alne in the early 1500's.
I live in Yorkshire, have some 1050 names in a GEDCOM that covers the entire world, Lickiss photographs etc.
The family seems unique, in that every single person with the name is related. I am still looking for someone that I don't have a family line relationship.
My GEDCOM is available to anyone who is interested.
