Albu i suppose that is quite dangerous if the first cousins then went on to marry their first cousins from those 5 unions
But if they developed any family health issues how would  you know if consanguinity or life conditions had affected them .

Not as bad as Egyptian royalty marrying their siblings !

It involved taking tiny bits of his teeth to specialists in other countries .

Maybe bone DNA is more stable than spit & swabs but less accessible for general public to extract
.i.ll raise the question next time !

It might be worthwhile asking the dentist for the tooth next time you have an extraction!

There is a lot of inbreeding on my mother's side, her family came from a farming village (Lode) near Cambridge. I was told that providing there are no underlying health issues this is quite helpful to family historians as you get a double dose if there are cousin marriages. If there are health problems it is very serious.

Using the shared surnames I found a cluster of 9 Americans, from 23 cMs down to 10 cMs, descended from Cornelis Pieter Jongewaard born in the Zaanstad (Netherlands) 1641. The ancestor of the cluster left for America, mine remained in the Zaanstad and my father came to England in WWII. So it does seem you can go a long way back, in certain circumstances.

Did Ancestry flag this group up as having common ancestors with you? Or did you find them by your own research?
I found them by my own research. Peter Calver of Lost Cousins recommends putting all surnames into the search function. I found people descended from a Ringert Jongewaard and expanded their trees to meet mine. They are shared matches to each other. Ancestry won't list them as common ancestors as they are too far back. I was interested that such distant matches had reasonable amounts of cMs.

With the new match function we can now add our relationship to known matches ...will that create new common leaf tagged ancestors

Out of interest
what dates are your common ancestors with more than one link ?

My mother has 4 DNA links to Nimrod GARDNER. 1756 of BUGBROOK Northamptonshire and his wife Susannah RODDIS 1756

& a few
5th cousins thru Richard Mawslbury1744(some don't show up because of spelling variations) but show thru his wife Hannah Higginson of Moreton Pinkney Northamptonshire 1751

Trees have been well researched !

The links go back further when descendency is thru younger children of younger children thru the generations .or children of older parents who can be a generation younger in years than their siblings but same generation in genealogy terms.

I've got a 20CM match and our closest known common ancestors seem to be born in the 1640s. We both descend from the same couple in two different lines which may explain how such a distant connection is possible.

Around 60 years ago in Lincolnshire there was a case widely reported at the time of two sets of identical twins who were also first cousins marrying. The mind boggles in any of their children followed suit and married their cousin. The consequences could be like those of Egyptian pharoahs.

I have found a number of common ancestors, using BMD records and Census records, which Ancestry haven't found.

When i looked at some Public members trees, it is clear that Ancestry do not use all the information that they have in their system.
