Help wanted to understand Ancestry.com ThruLines

[brigidmac]

I ve just helped a relative change her home person to herself and link her results to her tree...thru lines take a few days to appear after changes are made so hopefully we will see results soon .

Good luck .

Btw another.tip is to make sure that everyone has the next generation up on their tree sometimes thru lines  don't show to great grandparents but appear thru their parents

Thrulines.

Evaluate each person presented thoroughly including gathering multiple citations for each person.

One thing to check is for each person presented to Evaluate look at their Parents, then compare those parents with the person presented as the prior generation.

What I find is (I’ll just use male to male for simplicity):-
Our DNA match is Bert.
Tom is listed as Bert’s Father and flagged as Evaluate.
His Father Tom is seen on the family trees used as having a Father called Dick.
We then look at Tom’s Father who is presented as Evaluate is in fact called Harry.
So things are off here.
Harry’s Father in the trees is shown as Bill
Yet again we see Harry’s Father presented to Evaluate as John.
In the trees we see Ted as Harry’s Father.
We can also see a sixty year difference between generations presented as Evaluate.

Hence do not take Thrulines as Gospel more “As loose Guidelines”

Have you checked that they ( & you )

1) have trees

2)have put themselves not one of their ancestors as home person

3)& Have linked their trees to their DNA results

I don't believe step 2 is necessary.

I control some DNA tests. They are linked to a family tree, but not one I own, and they are not the home person.

Thrulines works just fine for these persons/tests.

wexflyer

yes i manage other trees+ dna too

so maybe step2 needs rewording as somewhere the person who has tested dna has to be linked to a tree for thru lines to appear .

Ancestry Thrulines just uses Subscribers Trees to compile the suggested relationship pathway.

At each point where Evaluate is shown on the suggested person the trees used to make the suggestion may or may not be owned by a person who shares DNA with the starting and ending person in the Thruline.

There are three necessary conditions for Thrulines to work:

(1) A DNA match
(2) That the DNA match is linked to a family tree
(3) Sufficient details on either your tree and/or your match's tree for Ancestry to deduce a common line of descent.

I have a thrulines match to a  5th cousin once removed. He only has one person in his tree (private but presumably himself). I have his 4 x great grandfather in mine (brother of my 3 x great grandmother). I only have name and date and place of baptism for this man, not his marriage or death. I have checked the line suggested by Ancestry and it looks correct. The information that lonks us must have come from other peoples trees as it didn't come from either of ours.

The minimum people in an Ancestry tree is two.

A tree of one does not save hence a tree of two can and is used by Ancestry in creating a Thruline.

This tree saved somehow. (his name redacted)

Thanks very much for all your comments, it puts it in a completely different light for me.
