Title: What is your smallest DNA match
Post by: brigidmac on Tuesday 15 October 19 12:59 BST (UK)
My smallest match on my mother's side is 6cm
The paper work was already done and we've both put same spellings and birth years which show we have mutual great grandparents
George Smith b1826 and Margaret Yates

I be also found connection s to Nimrod Gardner of Bugbrooke 1756 5th ggfather one is a 5th cousin 16cm
The other a 4th cuz once removed thru his son

On my father's side I have a 12 cm.match thru my  3xgmothe Margaret love b1840 Shettleston
I put surname Muir cited as birth father of her child and Shettleston in search function and came up with this match we have built back our trees and now have a thru line

Is it worth looking at small matches with mutual names + places ?

I have a 7cm GRESTY match which may prove maiden name of a g ggmother but this name is common in Wales and Lancashire

So, do you mean what's the smallest listed match that you can actually find a link with, rather than just the smallest listed match?

I found my smallest to date (6 cMs) through Common Ancestors, otherwise I don't tend to go that low unless I have a good reason.

Mind you, any new matches for me and the accounts I manage are a bit like hens teeth at the moment (i.e. nonexistent) so perhaps I will start looking more closely at, say, 15-19 cM matches that I haven't previously identified as a match either via Common Ancestors or Shared Matches. But NOT if there's no tree - 99 times out of 100 its a waste of time!  ::)

Yes I meant smallest match you can link to
I have some small matches with a name and place list but can't match actual individuals.

If you put a more specific location to
Place it might throw up interesting matches .I had a colour code group to Cheshire but have now added extra colours for Birkenhead and Audley in Cheshire but my Jones and Roberts are very much intermingled and have a tendency to marry other Roberts and Jones  I think a specific village in Wales might find where my Roberts side came from .

I've just checked and I have a definite one at 8 cMs across 1 seg. She is a 5th cousin. Her 3rd x grt grandmother was the sister of my 3rd x grt grandmother (she signed the marriage entry). Add - I share 13cMs with her sister!

I also have a 7cM match but can't find it at the moment.

Add- I have numerous Jones and Roberts lines in Denbighshire, Merionethshire and Shropshire ;D

My sister has an 11cM match on our Welsh line, I'm confident with this as he matches me at 102cMs, just goes to show how random DNA can be.

I think these examples go to show that when DNA connects it does match up with paperwork

Angelfish that does seem a really big difference.

I have found the occasional small (6cM) match which has been really useful.

For example, I have a 6cM match in Canada, who links back to my Dearling line in Horne, Surrey in 1750! Our mutual ancestors were sisters, and we share the same set of 6x Great Grandparents. (It took us a while to work it out:-)

Found another one at 6cM. This is a 5th cousin. I had difficulty matching her initially. I had our  4x grt born in Wellington, Shropshire but Ancestry had her 4 x grt as being born in Wellington, NZ  Good old Ancestry ;D

One of my smallest links with a tiny tree came up when I searched Shwartz not sure howhe links cos no birth year but son born 1901in Hungary . Gave me an alternative spelling for surname as Szaba

I've been trying to solve how American Schwartz family links to me ...looks like more matches from Europe use Shwartz spelling

The lowest matches on AncestryDNA are 6 cM. I have several at that level where I can find a plausible paper trail to explain the connection. However, at that level there is no guarantee that the matching segments are passed down from the suggested common ancestors.

When solving descendency thru SMITHS  sometimes the smallest mattches with an unusual surname holdes the key

I found a martch
turns out to be because  a great greatgrandson of my  great grandfather had two wives and the match  was great grandchild of the second wifes mother in law who I hadnt looked into before

When I knew which Smith they descended from I could fit them into my tree

(I only spread my tree that wide because I was helping an adoptee whose grandfather turned out to be the one with a second wife )

Sometimes 6cm matches can be really helpful if you're trying to break down a brick wall. I've got 4 matches with the same surnames in Kent that are related to 6cm, 9cm, 9cm and 39cm. I can see how they all relate to each other but not to me. Still haven't worked it out.
I've got another match who is 9cm but I think she should be more as our shared grandparents are my 3rd GG and her 3nd GG.

Yes vickey I would expect higher than that unless you only share 1 ggggparent

Thru second matches .family adoption.or infidelity.
Have you checked if you both match all 4 of the parentsbof common.ancestors ?

Post by: GingerVicky on Tuesday 24 November 20 20:36 GMT (UK)
I'm pretty sure we do share both sets of parents according to our trees we do but I need to check my other matches to see if they confirm it. I did wonder if one was illegitimate or adopted. Will have to investigate further.

Sorry Vicky ignore my last coomment
Ive been looking at my dna 3rc cousin.matches and comparing to my cousins matches to same person.
They can vary between 90cm and 6cm
When it comes to 3rd cousins once removed he matches one that I dont and I match one he doesnt

The dna painter chart is accurate
