Impossibly high DNA matches .! Possible explanations ?

[brigidmac]

I have seen a few higher than expected DNA matches & have a big data base
Followimg paper trail found out that one line descended from a child that was raised be grandparents as their own .so all descendants were a generation closer than recorded on censuses and suggested by thru lines .

This one could be something like that .
A DNA match  descended from   Annie b1902 daughter of Charles gdaughter of   Henry Eden b 1853  comes out  on thru lines as half 3c1R
Is a 116cm 5 seg match less than 1 %.chance could be that level

Another descendant of Charles half 3c1R thru daughter Ethel comes out as 40cm3 segs which is also high for that degree of removal .

Henry 1853 is brother of  direct ancestor Joseph Eden b1869 on record but could he actually be his father
Or could Joseph be the birth father of  great neice Annie ?


The parents of Henry and Joseph are Charles H Eden+ Ann Cheatham

[brigidmac]

In 1901 Joseph was a widower

I thought maybe he could have had children with first wife that a sibling had adopted but Annie was born after wife's death
I've never been able to find his first marriage wife's name or any children .

[brigidmac]

Charles could be father of josephs son b 1906 but
He emigrated to USA in 1905

His wife Jemima and children ethel.florence Alice and Ann 2 went to join him in 1907

Could Joseph have been Annie's bio father ...that would make more sense ;
the 116cm match
would then be half 2C


If Henry was also father of Joseph it would explain the higher  link to Annie's sister Ethel's descendant half 2c1R  which fits with 40cm
Match

What does anyone else

theory 2 is that there are some cousin marriages further up the line between CHEATHAM & Henry + Joseph  EDEN s grandmother Elizabeth BATERSBY s relations

[brigidmac]

Theory 3
If there are twins along the DNA lines would their neices and nephews    appear to be same relation as  their chlldren

[TreeDigger]

It's fairly difficult to try and answer this without knowing the exact (official, not theoretical) relationships as well as the generations between people.

Am I correct in assuming that..

* the 116cM and 48cM matches are great-granddaughters of Charles (1879) through Annie (1903) and Ethel respectively, and thereby 3rd gr.granddaughters of Ann Cheatham?
* that you are a 2nd gr.granddaughter of Ann Cheatham through Joseph (1869) ?
* the half-sibling relationship between Joseph and Henry (1853) is well documented? Or was it Ancestry that threw out a possible half-sibling relationship?

If you had other matches (and cM's) with more descendants of Ann Cheatham, it would be easier to calculate a possible theory I think.

Thank you for your reply

The match is a relative who I'm helping

I have some more information from generation above

Through sisters Ann Cheatham 1828  married Henry Eden  +
 Elizabeth Cheatham 1838 m Thomas NORRIS

They are all 3rd great grandchildren of Henry
Cheatham 1792 + Elizabeth Battersby

MR. My relative matches AB the great granddaughter of Thomas Norris 1863  by 22cm which is reasonable for 4th cousin
But the other great granddaughter of Thomas Norris  MJ is 97cm

MJ &  AB 2nd Cousins match by 265 cm which could also fit if they are only half  cousins

MJ has shared her match amounts with me for some of the other mutual matches

The half cousin was generated by thru lines from different spellings .thru lines are recalculating due to a tree change
Regarding descendants of Charles EDEN 1829  + Ann Cheatham

The 116 cm match has tiny tree does not show on thrulines but Is  gdaughter of Annie EDEN  1903 m Thames so should be 3C 1R if paper trail is followed

The 48cm match CB is 3C2xR on thruline
(2 generations younger than MR) her great grandmother was Ethel Eden1898 m Holdsworth  (sister of Annie Thames)
Whose father is Charles eden 1879 nephew of  Joseph EDEN 1869

Another 3C 1xR thru Annie + ethels brother William eden comes out at 19cm

There are several thru lines to  Ann Cheatham
(& Charles Henry Eden  )

That come up between 13cm and 38cm to 3c2R
Thru 2 different children.

And there are matches thru some of  her siblings  one 4th cousin is 55cm

I'm really sorry I can't put it on a chart . All I can do is take screenshots + try and edit

[TreeDigger]

That's still pretty confusing 

Does the enclosed diagram approximate the relationships within the family? (hope it's visible)

[brigidmac]

That's perfect thank you very much

So if Joseph was actually the birth father of Annie eden that would bump the large match up to 2nd C level

[brigidmac]

Do you agree with my calculation tree digger .

I did wonder  if Joseph was also  the father of
One of the Norris girls too
But she doesn't match the highest EDEN DNA match
