There are at least two branches of the Vincent surname that were early arrivals to North America. DNA research has been on-going for these groups since May 2006.  Family History research began about the late 1890s.  About 2008 it was discovered the two main branches of North American Vincents fall into two Haplogroups: R-L1 (R1) for northeastern America and I-M253/Z63 (I1) for the southeast.  Family websites for these two Haplogroups can be found here:
