The Cruwys Surname Project


Welcome to the CRUWYS/CRUISE/CRUSE/CREWS/CREWES worldwide DNA project. Cruwys is a very ancient surname which can be traced back to the small parish of Cruwys Morchard in Devon, England, in the 12th century. However, the Cruwys spelling only began to be used from the seventeenth century onwards, and in some families was not introduced until the early 1800s. A large number of variant spellings appear in the early records such as Cruse, Cruis, Cruwes, Crues, Crews and Crewes. The Crewes spelling predominated in Cornwall in a line which is directly descended from the Cruwys Morchard family. The name Cruse is more widely spread in the early parish registers and appears mainly in Devon, Cornwall, Somerset, Wiltshire, Berkshire, London and Sussex. The Cruise surname is mostly found in Ireland. The Crews surname is found predominantly in the south-west and south of England. It is also a common surname in America and it is thought that Crews in America evolved from the surname Crew. The DNA project now has a wide selection of results from a number of key lines so new testers have a good chance of finding a match. The DNA project is run in conjunction with the Cruwys/Cruse one-name study, which is registered with the Guild of One-Name Studies in London. Further information about the study can be found on the Cruwys/Cruse/Cruise profile page: The results of ongoing research are published on the project's blog, Cruwys news: The DNA project is open to every male with any variant of the surname. Y-DNA tests are currently available for 12, 25, 37 or 67 markers. We recommend that testers should order the 37-marker test, as this provides more information and allows different family branches to be identified. The cheaper 12-marker test can be taken as a preliminary measure, and will indicate if two participants have a potential match but an upgrade will be required to reduce the time frame of the common ancestor. The Y-DNA test tells you about your direct paternal line, which would be your father, your father's father, your father's father's father, and so on back in time. You must be male to take this test, and you should have one of the surnames shown. If you believe there is a Cruwys (or other variant) in your direct male line, although you have a different surname, you are also welcome to participate. If you are female, please find a male in your family tree to participate.
