I'm the admin of the Cruse/Cruwys project. Is the kit in my project? If so do get in touch with me and I'll see if I can help as I have all the pedigrees of the project members. The outline pedigrees are posted on the project's results page. A 37-marker match is not necessarily significant. You really need both parties to upgrade to 67 markers if you wish to investigate a match with a different surname.
