In 2017 a further genetic study using profiles of 50 Irish Travellers, 143 European Roma, 2232 settled Irish, 2039 British and 6255 European or worldwide individuals confirmed ancestral origin within the general Irish population. An estimated time of divergence between the settled population and Travellers was set at a minimum of 8 generations ago, with generations at 30 years, hence 240 years and a maximum of 14 generations or 420 years ago. The best fit was estimated at 360 years ago, giving an approximate date in the 1650s. This date coincides well with the final destruction of Gaelic society following the 1641 Rebellion and during the Wars of the Three Kingdoms in which Cromwell's forces devastated the country.
