Crawford Clan DNA Challenge

Image
Have you had your DNA tested? If so, did DNA help you answer a question? Based on Facebook posts I've seen, it appears that DNA is helping adoptees to connect with their birth family. In my case, I wasn't hoping to identify a close relative. Instead, I was hoping (and still am hoping) to identify my 5th great grandparents -- particularly on my dad's CRAWFORD line. It's been 3 years since I first spit in a test tube (autosomal DNA) and since my brother swabbed his cheek (yDNA). That's 3 years of working with various DNA results and few clues about this mysterious CRAWFORD grandfather. As I'm trying to learn more about our yDNA results, so I can make sense of how we might fit in the Crawford Clan, I've come to a couple of conclusions: There's too little data - I need more 5th, 6th and 7th cousins to do a yDNA test Determining relationships is VERY dependent on the accuracy of BOTH of our family trees

DNA Haplogroup

Thanks to some updates to the yDNA test I manage, my Crawford line (James Crawford - born 1772, died 1854) has been assigned a new Haplogroup: R-A13336. Previously, we had been grouped in the larger R-M269 Haplogroup. According to a Crawford project administrator, I also share the Y30725 terminal SNP with another match. It is my understanding that work is still being done to determine which is older: the A13336 or the Y30725.

Have you ever come across a new piece of information that sends your genealogy research in a totally different direction? I'm sure you have as most of us encounter this from time to time. Yesterday, I received such a piece of information. This wasn't a document but a DNA result - a yDNA result. Apparently, my Crawford line is its own branch with my closest Crawford match being a descendant of Edward Crawford of Overton, Tennessee. So, one of my new goals is to try and determine how this Edward Crawford might fit in with all of my James Crawford research. With only five Edwards in my database it is a relatively unusual name. Unfortunately, Alexander and Mary (McPheeters) Crawford had a son named Edward. Thus, there will be confusion in online trees as to the parents of Edward. In looking back thru my Kentucky research notes, I do have some data placing an Edward Crawford in Madison County, Kentucky during the time period of my James Crawford research. In 1795, Edw...
