Last night I was going thru some online Irish records of names and now I am on the alert for Sisney's so if, in my research, I find one over there, you will be the first to know. I did not find any as they could be anywhere. My search will be in the specific areas where some of the Battle of the Boyne soldiers were known to have settled and there are several.I have been told that many of the church records are in French so it will be an interesting adventure to find any records.
I just don't believe that the name Cessna came from Sisney, now that we know that they were a separate group. They just seem so different.Cessna is wayyyyy off for a spelling of Sisney.........but you never know.......so I will keep an open mind for that possibility!In the meantime, I will keep on searching for the Frenchman of Cessna lore.........and I sure hope he exists!
