The RAINS Families of Great Britain DNA Project has several objectives: 1. It is attempting to find links between the various regional RAINS families throughout Great Britain and the origin of this surname. 2. Within the Northamptonshire area it is trying to establish a common ancestor of the families who dwelt there for at least 400 years. Participation is open to any male with the RAINS surname (or a variation) who believes his ancestors originated in Great Britain.
