I just had my DNA completed with 23andme and was wondering if we have any information regarding the ancestry of Epyptian mummies.
Well, Wikipedia does have a page for it, so yes it has been done.
For example, Ramses III had the E-V38 Y Chromosome Haplogroup. Interestingly, most of the modern people who have a large preponderance of this pattern are West African. However, some of it is found all over Africa, and even in about 10% of modern Eqyptians. So I don't think a lot can really be read into it (other than that his recent lineage probably hailed from Africa somewhere).
