From ISOGG Wiki
A genetic family (also known as a genetic group) is a term used to define a group of two or more men who have an identical, or near identical Y-STR haplotype (DNA signature) and who share a common or similarly spelt surname. A genetic family is created when matching Y-STR haplotypes are aggregated together. The results are often published on a surname DNA project website.
Genetic families may also include men with dissimilar surnames to the rest of the family when it is suspected that a non-paternity event (surname switch) has occurred at some time in that man’s patriline (for example, due to adoption, illegitimacy, remarriage, etc).
