The Crook Surname Project is open to all who are interested in working together to find their common heritage through sharing of information and dna testing. All variant spellings are welcome. If your Surname is missing and should be included, we will be glad to add it. Please visit our website and add your family to the Patriarch Page. The Crook surname project is primarily focused on the male Y-DNA prospective but is open to mitochondrial (mtDNA) from the female DNA history too. Realize that males pass their Y-DNA from father to son, but not to their daughters. Females have no Y-DNA but pass their maternal DNA to both their daughters and their sons. Their sons will not pass their Mom’s mtDNA, which will come from the son’s mate. Please feel free to look through our list of Y-DNA & MTDNA results. We hope it may help our participants and others who are simply looking for their family history. Participants are encouraged to list their earliest known ancestor. This will help us all in our family history searches to find more family members. Please be respectful of everyone. We are all family.
