A DNA project has been launched for the Tingle surname, along with any variations such as Tingley, Tinkle, etc. The project uses testing on the male Y chromosome which is passed directly down the paternal line from father to son making it ideal for investigating surname lineages. The testing can be used to uncover, prove, or disprove connections between various Tingle lines and to also give clues about the deeper origins of the lineages.
Project participation is open to any direct paternal-line male Tingle descendant - i.e., a male whose last name is Tingle (or any variation of the surname) or a male whose biological paternal-line ancestry goes back to a Tingle but whose last name was changed at some point, such as due to adoption. Even if you are not a direct paternal-line male Tingle descendant, you can join the project by sponsoring the testing of a Tingle male from your immediate or extended family, such as a brother, son, father, uncle, male cousin, distant male cousin, etc.
