The Administrators of the Yearsley yDNA Surname Project have over 40 years of combined Yearsley surname research between them; from scouring original church documents in dark crypts, hiring on-the-ground professional researchers and paying for old Latin documents to be translated. We have amassed hundreds of trees from around the world and it is highly likely that we have a copy somewhere of yours. Our earliest trees date back to the 1400's.
Most of our Yearsley family tree research can be found published on Ancestry.com or held privately but are only available to yDNA study participants or fellow researchers.
