Our family members have been using different sites for DNA. Mainly some have used 23 & me and others Ancestry. For comparisons sake we loaded our results into GED Match. Which are resulting in no known shared DNA??? Our relationships are Aunts, first cousins, second cousins, third cousins and so on.

What is the margin of error and comparison here? Any explanation? Before you say it, yes we are for sure related!

Did you run a one to one comparison? Is anyone matching each other or are you all showing up as no shared DNA?

There is a small possibility that third cousins won't share DNA, and the more distant the cousins get from there, the higher possiblity but an aunt and first and second cousins should definitely share DNA with you.

How many people are testing? See my blog to upload free on My Heritage and Family Tree DNA. You will probably have the same outcome if someone doesn't know their parent isn't their parent. Could also be an adoption that is being kept a secret.

My heritage will take a few days to give matches and ethnicity but FTDNA is fairy quick. You can also upload your family tree GEDcom file.

Good luck. I know what its like at 40 to find your father may not be your father. It sucks when people keep ecrets about your own life.

You can also upload to familytreedna.com and MyHeritage.com for free - honestly, if you don't match on either of those sites in addition to gedmatch, then there is no possibility of an error or a bug or a delay in the system, there was obviously an adoption or something.
