Help understanding old family tree in Latin please
 

I'm looking at this old family tree mostly in Latin:
https://www.british-history.ac.uk/th...vol1/pp359-361

On the fifth line down is Jollan de Amund[eville] who married Eremetruda neptis C. Anm - I think that's what it says.

Neptis = granddaughter or female descendant, according to my Latin dictionary. What does the C. Anm bit mean, please, anyone?

Because C Anm is in capitals, I imagine that it is an abbreviation of the grandfather's name.

This looks as if it is a pre surname tree. So is Amundeville somewhere local, or might it be on the continent? I've looked in the Nottingham Visitation and no obvious names leap out at me.

The reference appears to come from:

Mon. Angl. Dugdale's Monasticon Anglicanum, ed. Ellis, etc. 8 vols.

It is possible (though unlikely!) that this will point you towards orginal sources used

The people on the left hand side have a surname, though - Bussy. The stuff I was looking at online seemed to be using de Amundeville as the other family's surname.
"Jolanus" (Jocelin) and Beatrix on the third line down owned land in Lincs and Notts and seem to have lived in Lincolnshire - apparently Beatrix founded a hospital for the poor in Elsham, Lincs, beore 1166. And there is mention of that in the Monasticon Anglicanum - thanks for pointing me in that direction! I will look through it some more and see if I can find Eremetruda.

Aha, a footnote on British History Online says "family of Mondeville, dept. Calvados, arr. and cant. Caen; see Clay, Amundeville, pp 110. So it does look as though the name originated on the continent, yes!

Somewhere else I found that Stoke Mandeville was called after the Amundeville family.

Interesting, thanks.

Perhaps C.Anm is meant to be C.Amn. then?

OC

Edit - or perhaps Anm stands for annulment? Lots of online trees claims she was divorced, no supporting evidence of course!

Further down in the tree, C. stands for county, but I can't think of one beginning with Anm.

County Antrim

On this one the text is slightly different
