Annie first of all you are NOT dumb.This Ydna (or any dna) stuff is Very difficult to understand for we layfolks out here.
I sent you an email about this and hope that it will better help you to understand it, but again I will pass this on in case it might help others to get a better grasp on it as well from a Really Simplified explanation.
Pretend you are at a slot machine and you pull the handle and it comes up Apple Orange Pear.This means you did Not win.Then you pull the handle again and it comes up
Apple Apple Apple...Yay, you have a win or a Match.
This is a Very Simplified way of understanding your Ydna result numbers.IF your tested male Moody has a Match to someone else in our Moody Ydna Surname Project, they will most likely match up Number for Number Exactly (Apple Apple Apple) or they won't (Apple Orange Pear).
In some cases they will be one or two "mutations" off from each other BUT, they will still be of the Same HaploTYPE and 9 times out of 10 these mutations occur at what are known as Rapidly Mutating Locations on the DYS chart, but it in no way means you are still not related to that line via Genetics/blood/HaploType etc.
The bottom line is that you are a male born MOODY that matches in some form to other MOODY's of the SAME HaploType.
Using our group as an example...we are the I1d-N -Norse group, (formerly I1a-N).We have I think 12 MOODY males now represented in our group, one or two of them are not shown but I am in email contact with them.The one thing we all share is our "I1d-N" HaploType.That does not change among us.We also share Exact 12 marker matches and most of us still match exactly even at 25 markers. However, for some odd reason that no one can seem to explain, in the 3rd panel or in the 37 marker part of our results, we have several Mutations and 99% of them are at these Rapidly Mutating markers.We are still MOODY's though and we are still All of the Same HaploType...again, that never changes.
Now...to create another really simplified explanation of how the Ydna may NOT match to ones given name is this scenario...
Let's say a girl gets pregnant by a man whose last name is SMITH.This man has no intention of marrying her nor she him, but the bottom line, she is carrying his child.
Nine months later that girl gives birth to a son whose REAL last name would be SMITH, but for whatever reasons, she gives this son of hers her family last name of MOODY.
That means that this son will be raised among her MOODY relatives, he will only know his grandparents as MOODY's...aunts, uncles, cousins etc. on down the line.
That's the only family he's ever going to know through his growing up years.He has No idea that his Father's family is Smith.
Then this son grows up and he gets married and he has a son.
This son's last name of course is also going to be MOODY.He's only going to know his Moody relatives as his grandparents, uncles, aunts, cousins etc. too.
This son grows up and he gets married and his wife also has a son and this sons last name will also be MOODY.
So eventually this son grows up and has a son of his own (again of course last named MOODY), and he decides to do a Ydna test.When this ~presumed~ MOODY son gets his Ydna test results back, he finds out that he matches to NO Moody's anywhere.He's stunned by this and cannot figure it out. Well, he says, I Know for a Fact that my grt. grandparents were MOODY's, I have their birth records and marriage records and the birth records of their children etc. etc.But still his Ydna test results say he does NOT match to anyone of the last name of MOODY.
BUT, he does have some close matches to several of the SMITH surname.This will be his first clue into the fact that somewhere in his Moody family past, a female got prenant by a SMITH man and that female gave that child (a son) born to her, her family name or a family name of MOODY.
This is why documentation means doodly squat in a Ydna test result situation.Yes, by Relationship you are of the MOODY family you were raised in, but you are NOT a blood-line or genetically linked son of that lineage line.
You are a SMITH!
The other situation that could also have the same Ydna outcome results is if a son was taken in as a result of abandonment, or a death of both parents due to sicknesses of the past (small pox, typhoid fever etc.) and these children were Adopted by a MOODY family and of course those male children would then have the last name of MOODY which the male born sons of that line would also pass on to any male born sons they had as well. HOWEVER, they would No more be blood line or genetic MOODY's than the above scenario male born sons were.
This is where you can find out perhaps just which line of family name you do belong to.IF you have done a Ydna test and you are Not matching to anyone of your given surname, Upload your Numbers to YSearch and see who do match closest to...which surname do you match closest to.This could be a HUGE help to you.We have 2 people in our own branch (I1d-N group) who are Not male born MOODY's by name but they match pretty closely to us and they too are of the "I1d-N" HaploType, meaning that somewhere in their family's ancient past a MOODY was the father of a son in their family tree.Whether they like it or not, that's the case...the Ydna doesn't lie.It has no opinion or agenda, it can't decide anything for itself. It IS what it Is.
I hope this really Over Simplified version of ydna test results and how they can really mess with your outcomes, helps some to realize how this all works.It is so complicated, and they are still learning new stuff all the time about it.
Your Ydna results that don't match, could go back Thousands of years.There is in some cases No Way to find out just who your exact family line may be.Due to the Mutations which occur over the years or hundreds or even thousands of years in some cases, may never be found, But, you can do the YSearch thing and ~Perhaps~ find some Other Surnames to whom you do closely match and that could be a clue for you and an area for you to start researching.
That would be my suggestion.
Anyway, I hope this is somewhat helpful and I haven't confused the situation further.
