Origins of surname

Mahy is the Ardennes form of Matthieu, so the surname is derived from a personal name from this north-eastern part of France.

Early records

Mahy is very much a Guernsey name, and all those found in Jersey are believed to originate in the sister island. We were sent a skeleton tree which we were able to expand with the help of church records and online trees, but the latter can be very misleading, including one of the main lineages which shows dates for parents of a child born a century earlier. We have done our best to extract data to create the tree below.


  • Mahy
  • Mahie
  • Mahier, possibly a variant but we show it as a distinct family
  • Mahe
