As a surname, Harry is one of those that are often confused with a firstname or, as in my case, (William Harry Chapman) it is confused as being the diminutive of Henry. As with my father and several cousins, Harry is used as a mark of respect for ancestors who had Harry as a true surname.
The surname Harry is found widely in Cornwall (where my roots come from) but is also quite common in Wales & Ireland. The idea of the project is to concentrate on the Harrys that have links with Cornwall. That way I feel we have a better chance of making connections between our mutual ancestors and descendants - however, as it is entirely possible that some Cornwall Harry's have origins in Wales & Ireland, and, of course, many will have migrated to the four corners of the world notably the USA, Australia, New Zealand, etc. so all are welcome.
Ideally, I would hope to use the project to help those with Harry connections to unravel profile conflicts in Geni. There are 1093 Harry profiles on Geni and 107 documents so there is already quite a bit of material to work with.
