Hi all.
An intriguing DNA match has come up on my wife's results. Someone with a match of 459cM which Ancestry kindly flags as a possible 1st/2nd Cousin. However there are some difficulties with this.
This person is exactly the same age as my wife, which would indicate (looking at the site DNAPainter) that the relationship is of the order of half-1st Cousin or 1st Cousin once removed. For this person to be a cousin, the common ancestor must surely only be of the generation of my wife's grandparents. The problem is that both my wife and the other individual have very detailed trees going back at least three generations, and are both based in completely different areas of the country - the Midlands and London. We're thinking the only possibility is a non-paternity event, but the only time an individual from one tree was in the same geographical region as the other was my wife's father, who spent some time in the army at round about the right time.
If he was the originator, this would make this individual my wife's half-1st cousin. Is that too close for the above-mentioned DNA result?
