What I meant by the naming thing. Because of large families with a lot of people with the same name, which was a hangover from the defined Irish naming structure is First son after paternal grandfather, first daughter after paternal grrandma, on a daily basis, names could be confusing. So while a person might be christened Patrick John, to differentiate from his dad having the same name, the son might be known as John or Sean. It makes tracing more interesting.
Interesting about Sheringham and the US Air force connection. Not sure where I read this, but because of the airbases in Norfolk, Sheringham sent a lot of kids to the US. Glad you had a good adoption and reunion.
