Hello everybody
Im trying to help a friend who has took a dna test with ancestry and has a dna match of 1st/2nd Cousin, The cousin shares 869 cM across 38 Segments the longest being 87 cM .
My friend was born in India and came to England in 1950,s and would love to find some family members, She has contacted the match but cannot work out how they are related.
any help would be really appreciated, {The match does not have a family tree}
many thanks julian

That is a high cM and gives a 97% probability of a 1C match or 3% at 1/2 1C or 1C1R.
Expanding sideways at Great Grandparent level and building each family member’s branch to as near to previous generation level will help quite a lot.
Meanwhile if you can ID the DNA match by name then you can build a probable tree for them.
I have a 364 cM DNA Match and built a tree for them (see my thread on this) but as yet I still have not found a link to my tree.
The bigger the tree your friend has the better chance of finding a link.
But as I have often said if the DNA match has a user name like SkyDiverInToABucket you have minimal chance of finding a pathway, but using Shared Matches may help.

It could be a first cousin, a great niece/nephew or a double relationship.
Painter is one of the best ways of seeing what the possibles are.

Many thanks for the information, It is quite difficult to build a tree as the lady im trying to help really wanted to find her mother in India {possibly not living now} as she has no family members to ask and very little information.
She never knew her father and only vague memories of her mother.
thankyou for your time and help.

Many thanks i will take a look at the site, Could i ask what is a double relationship please ?
-
A double relationship is if you are related through more than one line. I had a puzzle with a third cousin who I knew was related through my paternal grandfather's line as a third cousin. His DNA was showing as much closer. I traced back and found that he was related through my paternal grandmother's line as well. I have quite a few of these in my father's line, as many were in the same small area since mid-1700s.

It maybe that it becomes a waiting game hoping that a sibling has a DNA test in which case a high cM match of c2600cM could be indicative of a close sibling relation.

Many thanks to everybody i think it will be a waiting game.

Have you looked at her shared matches to your friends highest match maybe some of them will have trees and you can see if there are any names coming up .
It's also worth contacting the people with no trees and ask if they have any connections to India and one or two known surnames.

Hi, you need to look at the shared matches of your friend and this cousin. Build up their trees, and look for common ancestors, but remember you are looking at what has been recordered, and that is not always the truth! This is how I discovered my grandmother had an affair which resulted in my father. Jayne

I have family in India and the Families in British India Society (FIBIS) helped me find their names and their history! They do it for free but do ask for a small donation. I'm not sure how they're working now with Covid-19, but they maybe able to help. :)

Many thanks for the help appreciated will give them a try.

There are several relationships this size of match could be. Dont forget half relations, half uncle or aunt. The shared matches comment is a good one. Build groups beginning with that match and share relationships. Then go to the next best match that is not in that group and do the same. Soon you will have relationship groups. Study the available trees from those groups and identify the most recent common ancestor. It takes work but it will pay off.
