The Treble surname project welcomes anyone to join who — 1. has a connection to the Treble surname. This connection may be genealogical or may be genetic or both. The genetic connection may be autosomal DNA or Y-DNA or both. The Treble project welcomes individuals to join who have a surname other than Treble and whose Y-DNA findings (i.e., their STR results and/or their assigned clade) are similar to the ever evolving picture that continues to develop regarding the Y-DNA findings for those with a Treble surname. 2. are willing to 'Opt in to Sharing' their Y-DNA results. The importance of sharing one’s DNA results can be stated no better than this excerpt from the R-U106 (R1b-U106) Y-DNA Haplogroup Project — “to participate in the process of discovery, and share the results obtained, because DNA testing is all about sharing, and without that sharing, it’s meaningless.“
