Contact your Nebula Matches to Encourage them to Set Paternal/Maternal Ancestor Locations on the YFull YTree

You may have noticed in the last weeks that the YFull tree is starting to become deluged by samples from Nebula.

My lineage of J2b-L283 alone has seen about a dozen new samples from Nebula in the last month or two.

You may have read in some forums where customers have lamented that their match disappeared from the YFull tree without having set a country and regional code.

Luckily there is something you can do about it.

Contact your Nebula match(es)

Keep in mind that many Nebula customers are health-oriented and may not be interested in male or female line relationships, especially those that may be distant.

Who is interested to advance the research into your lineage's origins? Likely only you and the others in your lineage, unless you are a uniparental line descendant of someone famous like Genghis Khan or Béla III of Hungary.

So the onus is on you to contact your Nebula matches to politely ask them to set their paternal/maternal ancestry codes in order to advance the research into your common origins.

You may even offer to pay for it if they are not able or interested in doing so themselves.

A few weeks ago, I contacted a half-dozen or so Nebula samples from my own line of J2b-L283 and one interesting new sample in J2b-M205 using the YFull messaging system. From my outreach, I got one reply from a customer who subsequently agreed to set their paternal ancestor location and allowed me to pay for the analysis. A second man also subsequently set his paternal ancestry without answering me.

So I didn't have a high success rate but I was able to advance the research into our origins by retaining some of these guys on the YFull tree.

How to use the YFull messaging system

  1. Click the mail icon at the top right of the page
  2. Below that, click the "New Message" button
  3. In the "Recipient" field, enter the 5 digit number after the "YF" in their sample id
  4. In the message you can say something like this:

Dear Sir,

My name is _____ and I'm reaching out to you __(YFull sample id)__ on behalf of the men in your line of _____.

Your sample is a child of _____ that appears to have deeper origins in _____. Your closest relative on the tree is ___ who traces his male line to ____.

Where do you trace your male line descent? Please update your sample's paternal origin on YFull to reflect this country and region if you know it.

We are an intriguing haplogroup that originated mostly in ____ and likely spread elsewhere through ____ during the time of ____.

Link to Facebook Group/YouTube content/Y Heatmap or (replace SNP with their lineage)

If you are not interested to pay the $49 YFull analysis fee yourself we may be able to find a relative to sponsor it.


You may also contact me directly at ___@____

This message will be forwarded to their email address.

If they consent to allow you to pay you can forward the email chain to and ask for them to send you a payment link for the sample.

  1. I like it Hunter. Hopefully it meets with success. Thus far, I haven’t any matches from Nebula Genomics. But one never knows what the future will bring.

    I want to see FTDNA offer a WGS. Then there’s samples there I would definitely upgrade.
