What sources suggest Blandina as the daughter of William Marshall?

Comments

I’ve been sent those names by a cousin from MyHeritage.

A family tree from other site also has same names.

What other site?

FamilySearch?

& other site:  davistree.info/getperson ... Uriah Davis

I managed to find both of these.

https://davistree.info/getperson.php?personID=I42470&tree=UriahDavis1 does show her as the daughter of William Marshal but cites no sources whatsoever.

https://www.familysearch.org/tree/person/sources/L6YT-HMK shows her as the daughter of William Marshal and cites:

• urn:familysearch:source:2644080679 : as an old G2G post explains this is basically an untraceable reference carried over from an earlier version of their tree.
• https://www.geni.com/people/Blandiane/6000000002005805216?through=6000000000339998532 this has no sources and does not give her parents.
• Complete Peerage-v11-p42 possible wife : we have this on Adam de la Roche's profile already. It makes no suggestion about her parentage.
• Ancestral File (TM), data as of 2 January 1996. Searching the current version of Ancestral File, there are ten entries for Blondiane, but only two cite sources, giving the same set of things that look like links but aren't:
  • http://fred:8080/cds/ark:/fs.lls/c627643
  • http://fred:8080/cds/ark:/fs.lls/c627670
  • http://fred:8080/cds/ark:/fs.lls/c627679

I can't see any historical source showing her parentage. The only mention of her seems to be in Adam de la Roche's charter cited in Complete Peerage.

Did you check the MyHeritage info?

Record Match from Filae Family Trees

is in box under that for Blandiane Marshall.

---

There are over 1000 trees on MyHeritage with Adam Roche and Blondiane in them. I haven't got time to look through them all!

I tried searching on Filae trees but was not successful. Maybe one has to be a member to search thoroughly.

All I am seeing is trees copying trees with no historical evidence.

Thank you for your time & effort on this question.  My cousin in NZ is a member of MyHeritage so I will ask her about it.  Kathryn M D-R Australia

Family Time Line

has Blandiane Marshal de Pembroke.

---

I can't find a site called Family Time Line. Can you provide a link?

---

At end of page:

ancestors.familysearch.org

---

Do you mean this page https://ancestors.familysearch.org/en/L6YT-HMK/blandiane-marshal-de-pembroke-1164-1193 ?

If click on View All under Sources it is the same FamilySearch page I discussed above.

---

It was written only as I said.

You have matched it with your link so that’s good to know.

Thanks for that.

Some family trees on MyH have Isabel De Clare / Strongbow born 1172 as mother of Blandiane who was born 1164 that is 8 years before Isabel.
