Cousins relationships
« on: Thursday 21 May 20 22:19 BST (UK) »
I am trying to solve a non paternal event (NPE) in Germany from 1959. An autosomal DNA match has turned up on one of the big genealogy sites that suggests either 1st cousin twice removed or 2nd cousin once removed. Unfortunately, we have only maternal ancestry completed on our tree so far. But I need to know how many ancestors to try to research, to know which line this match is connected to. However, the owner is not replying to my emails. Can anyone advise please?

Do a google search on "Cousin Relationship Chart".
That will show various charts from various sites - such as http://parkinglevelfour.ca/family-history/71-cousinchart

Thanks for that KGarrad. I have seen these charts but was hoping someone could help me with how many generations to try to look into (eg. how many potential trees I have to create in order to find the MRCA). Searching German records with a language barrier is proving difficult and time-hungry. Hopefulone.

Have you used the Shared cM tool to narrow down the potential relationship levels?

You did not say which site you are using, but the next step would usually be to use whatever grouping functionality the site offers to pin your match down to more specific lines in your tree. If there is any identifying information at all for the match try to develop a tree for them.

Following on from Craclyn's advice, can you run a shared match listing with your match?  Most of the sites have that facility. That should narrow down the possibilities.

Number of generations depends which way the relationship is.
Your First cousin twice removed (1C2R) could be your First cousin' grandson / daughter, in which case shared ancestors would be your grandparents
Or your 1C2R could be your grandfather/ mother's first cousin, in which case the shared ancestors would be your 2 x great grandparents. - 2 generations further back than the first example.

Your 2C1R could be your mother/ father's 2nd cousin, so shared ancestors are again 2 x great grandparents.
Or child of your second cousin, so shared ancestors are 1 x great grandparents.

I hope I got that all right - it's what my FTM software told me!


I have two matches who are approx my age (sadly over 65!) first cousins to each other but a generation different to me. Their great grandmother was the older half sister of my great grandmother - almost 30 years age difference between the two ladies.
Berks / Oxon: Eltham, Annetts, Wiltshire (surname not county), Hawkins, Pembroke, Partridge
Dorset / Hants: Derham, Stride, Purkiss, Sibley
Yorkshire: Pottage, Carr, Blackburn, Depledge
Sussex: Goodyer, Christopher, Trevatt
Lanark: Scott (soldier went to Jersey CI)
Jersey: Fowler, Huelin, Scott

Sorry! I don't do DNA, and want nothing to do with it! ;D
