Btw The populations showing closest relatedness to Roma (Gypsies) were Punjabis, Kashmiri Pandit and Sindhi.

>To learn about the source of the South Asian ancestry in Roma, we inferred the pairwise IBD sharing distance between Roma and various Indian groups, using GERMLINE to compute an average pairwise sharing distance between Roma and 28 South Asian populations (24 Indian groups from the India Project, Pathan and Sindhi from HGDP and Punjabi and Gujarati from POPRES). To simplify the analysis, we classified the samples into 8 groups based on geographical region within India: North (n = 38), Northwest (n = 235), Northeast (n = 8), Southwest (n = 16), Southeast (n = 59), East (n = 11), West (n = 42) and Andamanese (n = 16). We observed that the Roma share the highest proportion of IBD segments with groups from the Northwest (Figure 3b). Interestingly, the two populations in our sample that show the highest relatedness to Roma (Punjabi, Kashmiri Pandit) are also the populations that have highest proportion of West Eurasian- related (ANI) ancestry. To control for the possibility that the high IBD sharing could be an artifact related to high ANI ancestry, we recalculated the IBD sharing regressing out the ANI ancestry proportion and observed that the Roma continue to share the highest IBD segments with the northwest Indian group (Note S3). These findings are consistent with analyses of mtDNA that also place the most likely South Asian source of the Roma in Northwest India
