How do you know The sr. Thomas was not a citizen of the U.S. Shirley? Even if he never filed papers, I believe he waould have been granted citizenship by marrying a citizen. There is a publication "Immigration And Naturalization Records", authored by P. William Philby. (Huge tome, several supplements) Might try scoping that out. But there were several major & minor ports on the eastern seaboard of the U.S. & Canada. Many ship's manifests were never archived and for those that were, many were not indexed or easily available. Dick May you live to be a hundred, with an extra year to repent!
