Hello, I have done fair amount of research into my genealogy. I have found extensive info on many of the family trees yet have hit a wall with my paternal line. I have only been able to trace back to my grandfather, his father, my ggrandfather, is a mystery. I have only found a marriage certificate and some minutes from a church meeting. Would the y-dna test be the most revealing? (My brother did an Ancestry test that was interesting but not that revealing.)
In this case, I would recommend two options: 1. Ancestry.com – If you choose to take their DNA test, you can also take advantage of their family tree feature. Your DNA test results would be compared to other samples in the database. Combining this, with a manual lookup you can do, you might trace relatives on your father’s lineage. 2.LivingDNA – LivingDNA provides a separate unique analysis of the paternal lineage. This analysis will give you an in-depth picture of your father’s heritage. The only drawback is that LivingDNA database is relatively small (compared to ancestery.com and other big competitors). You can bridge that gap using GEDMatch service, by uploading your raw DNA data (acquired by LivingDNA). You can read more about GEDMatch here. Good luck and I hope you would find what you are looking for!
Which is all very well, but do these kits work and deliver the service they promise and what about the wider ethics and implications of home genetic testing? Is it always wise for generally under-informed, under-prepared consumers to meddle in the highly complex, nuanced arena of genetics, risking confusion, complacency or even outright panic and anxiety when confronted with ostensible “bad news” (which may not even be true)?
A DNA paternity test can answer a multitude of questions. Which is why when deciding to get a DNA paternity test, the purpose should be carefully considered. A DNA paternity test for peace of mind, where the samples are collected at home, cannot be used for legal purposes. The added expense of maintaining the strict chain of custody required for legal testing, where samples are taken at an authorised collection centre, may not be necessary.

I’ve been working on my family tree for decades. When I took the AncestryDNA autosomal test, the ethnic results matched my expectations, with mild variations. I knew my mother was of completely Irish heritage, but I came up 58% Irish, so apparently some of Dad’s British ancestors were Irish, not English, for instance. The section that matched me to other DNA test-takers was also accurate. I recognized a couple of my second cousins listed there. Other people had taken the test but hadn’t created a family tree, so there was no point in contacting them to figure out which ancestors we had in common. Be sure you’ve done some research on your own family–these kits do NOT tell you where you grandparents came from, or their occupations, or their names. They tell you how much of your DNA is common with certain nations or areas. I know I have some Germanic ancestors, so when my kit said “14% West Europe” and that turned out to include Germany, France, Netherlands, Belgium, Luxemburg, and Lichtenstein, it made sense.
Another key customer type could be people like myself, hurtling through middle age, perhaps just starting to feel the cold bony hand of mortality clamp down on their shoulder. People, who, in the past, may not have exactly prioritised their health, who are starting to wonder what may be in store for them and who are in the (“Hypochondriacs R Us”) market for some hard-core insight and advice.
