The following is the e-mail I received with news of the sale offers.
"There had been a thriving Armenian trading community in Surat since the 17th century and there was some inter-marriage with the local population. When Theodore [Forbes] met Eliza it was common for British men to begin relationships with Indian women and to have children, even if they already had a family back in Britain.There is very little in the scientific literature on haplogroup R30b. It was first discovered by Palanichamy et al in 2004.5 Chaubey et al surveyed around 12,000 mtDNAs from across India as part of an investigation into the phylogeography of mtDNA haplogroup R7 in the Indian peninsula and briefly discussed R30:
Susan Harvard, who has been researching Eliza and Theodore’s relationship for almost 30 years, believes that the couple were married in the Armenian church in Surat in early 1812, shortly before he was posted to Mocha in current-day Yemen. However, it may not have been legally recognised.”
"Haplogroup R30 splits into two subclades R30a and R30b, the former supported by ten coding region substitutions and the latter by 24 coding and control region mutations. Similarly, in haplogroup R31 a new subclade R31a can be distinguished by 17 control and coding region mutations. Coalescent estimates suggest an ancient branching pattern in hgs R30 and R31, dating back almost to the earliest diversification of the superhaplogroup R itself. This most probably occurred soon after the out of Africa dispersals into the Indian subcontinent."6I have only been able to find one paper which sampled mtDNA from Armenia. Harutyunyan, Khudoyan and Yepiskoposyan took samples from 741 self-identified Armenian males in four regional areas of the country. A further 94 samples were collected from the Armenian community of London.7 However, the researchers do not appear to have published the sequences or the haplogroups. They only sequenced the hypervariable region and did not test any coding region SNPs. It is common to find people with identical HVR1 sequences who are in completely different haplogroups. (Note, however, that population geneticists are asking different questions from genetic genealogists and for their purposes it is the relationship between the tree and population history which is important rather than a well-resolved mtDNA genealogy.)
The probability of having DNA from all of your genealogical ancestors at a particular generation becomes vanishingly small very rapidly; there is a 99.6% chance that you will have DNA from all of your 16 great-great grandparents, only a 54% of sharing DNA with all 32 of your G-G-G grandparents, and a 0.01% chance for your 64 G-G-G-G grandparents.9
