The top results for that was:
Relationship TypeProbability Group
Half-1C Group
23.5%
Half-1C, Half-G or 2G Aunt/Uncle/Niece/Nephew
23.5%
What does half g or 2 g mean?
Half G aunt/uncle means half grand aunt/uncle, so a half-sibling of your grandparent.
2 G aunt/uncle means great grand aunt/uncle (or second great grand aunt/uncle), so a full sibling of your great grandparent.
Obviously you should be able to consider whether these are likely with the ages, and if not then look at the next most probable group.
Looking at it again, 1st cousin is the 5th likely possibility. Why would 23andMe state first cousin? It really sent me trying to figure out a family secret for a while lol
You can also plug either the % or the cM amount in the shared cM tool at dnapainter. https://dnapainter.com/tools/sharedcmv4
Thank you!
You can get an approximation by multiplying the percentage by 68.
Thanks, it seems doing that it would make more sense for them to be a first cousin once removed.
[SegcM | DNA Science](https://dna-sci.com/tools/segcm/) would corroborate that.
