Why So Many English Families Never Knew They Had Irish Roots

An Irish grandmother becomes a Taylor after marriage. A family settles in Manchester and stops mentioning where they came from. A surname changes just enough that nobody thinks to question it. By the time a few generations have passed, everyone assumes the family was always English. Millions of Irish people crossed into Britain during the 19th century, and plenty of their stories quietly disappeared. Sometimes all that's left is a single letter in an old census record. It's worth checking what that letter says.
