The focus of this project is on the surname Molyneaux/Molyneux (and other variant spellings). Mx is used as an abbreviation to refer to any spelling. The Y-DNA portion of the project is open to any male who descends from a known, or previously unknown, direct male Mx line and has ordered/taken an FTDNA Y-DNA (paternal ancestry) test. The autosomal DNA (family ancestry) portion of this project is open to males and females who descend from a male or female Mx. You can join if you have ordered/taken the FTDNA FamilyFinder test, or if you have taken an AncestryDNA, 23andme, or MyHeritage test and have uploaded those results to FTDNA (this is a free transfer upload).
