My Northern European family, like many families in the USA, has added African -American, Hispanic/Native American and Asian extensions to its tangled branches. An old Sunday School song says...Red and Yellow, Black and White, They are Precious in His sight. While rather dated in its racist overtones, the folks referred to in it are a pretty good description of what my family has become in recent years. For someone like me who is interested in humanity in all its variation, this has made for some interesting, challenging and fun genealogical searches.
With the advent of DNA testing to glean genealogical knowledge, this has opened a whole new feast of intellectual inquiry. A few months ago, I was finally able to pony up for two 37 marker Y-DNA tests...one for my African-American son-in-law and the other for my wife's cousin, a direct male descendent of her Hispanic maternal grandfather, who origins are obscure but with a paper trail back to Indians who lived in the mountains of southern Nuevo Leon in northern Mexico.
To come to the point of this already too long blast of loquacity... I still haven't gotten haplogroups from Family Tree DNA. After calling and talking to their representatives, I was told they had been submitted for "backbone" testing. I was told that the company would be testing much more about the Y-DNA sample than normally gets tested. But the reps were quite vague about what EXACTLY they were testing. Does anybody on this forum know what exactly goes into a backbone test?
