Hi, It looks like MyHeritage teamed up with 23andMe based on the news letter they have just sent out. Subject line was "DNA: exciting new discoveries via 23andMe". Have no idea what the service is like let alone cost. Further to what Debbie wrote, just wondering what it cost to do the DNA on Richard III, maybe it could be an option for lines that have died out, can not see close relations objecting if they died over 100 years ago as they be 6 foot under as well. Regards, David J Grimshaw (or is it Grimason?) Genealogical Researcher of the "Grimason" surname and variations of the "Grimason" surname World Wide. A One Name study registered with the Guild of One Name Studies (GOONS): 6138 formally 2962 The "Sherlock Holmes" of this family according to some.
