Douglas Sheard probably knows the answer about
the Leeces as he has his tree. You could write a letter
to IOM newspapers [The Examiner] they are online. Give
details about your Moore family emigrating to Canada &
your Homecoming this summer---they often publish such
articles with people trying to contact distant relatives.
Do you belong to IOM family history Soc.? It is based
in Peei & maybe some of their members might be able
to help. Many do not visit this Board or have e-mail.
