One way to expand our branch is to track down other people who look like they might be in the R-BY3483 haplogroup and contact them to let them know - knowing that taking the test isn't a complete shot in the dark, that there are others out there they'd match with, might encourage more to take one of the available tests (single SNP, SNP Pack or, ideally, Big Y).
I don't have any solid close matches, just a GD 0 at 25 markers to a Swiss man, which makes some sense now I have the Big Y. So I have contacted him.
I spoke to Frank on the R1b activity feed and he said that didn't have any good matches.
So what about you others?
For example, Kightley is an interesting and, relatively, rare locational surname derive from Keighley in Yorkshire. A good working hypothesis would be that all people with that surname descend from the same male line (often an important local individual). A Family Finder and Y-37 would be enough to test this. An advantage it has is being an English surname so, unlike my Irish ancestry, you can often get 300-400 years of a paper trail worked out, which would allow you to identify 4th+ cousins that are recommended for Big Y testing.
There are some on here:

including a few living Kightleys:

Although note the variation:
https://www.geni.com/surnames/kightly
appears to come from Knightly (although that could also be a variant):
Edward Kightly
So anyone else got any good Y-STR results and/or a sufficiently deep tree to identify distant cousins who share your male line?
