What are good books and reference material

You are aware of your haplogroup? 

No, searching for it.

Yes, that's why I am here. Besides, I am an inbreed. We actually were nobles once, but, now we lost it. Anyways, my father tells me that our real ancestors were giants, I have this much of knowledge.

Now the times have changed though, and I don't know how much of admixture I myself carry. 

That we too don't know, however, I know that they migrated from the northern indian regions, long time back, and became land lords in certain regions of west-south India, which would be maharashtra. There were kingdoms of peshwa, and interestingly, even under british rule, my grandfather too was land lord and tax collector. The status did not change even under british rule.
