To all of you quoting your line back to Harold, it is your job to prove every connection between everyone of your ancestors. The most problmatic area is between 1700 and 1350. If your sources isn't primary (or even secondary), you do not not have Harold as your ancestor.
Denise, Bengt-Olof, Katherine and Graciela, I have not checked your lines, that is your job, if you personally haven't checked your line back to Harold, please sever your line where you are unsure.
Nice in theory, Remi, but it's much simpler than you imagine. If someone's connection to Harold runs through many generations of royalty and nobility it might only be necessary to prove a connection to one of his descendants who lived hundreds of years later.
For example, any of several dozen colonial immigrants to America have fully and completely documented lines back to Harold. Prove your connection to one of those immigrants, and the rest has already been done.
Jethro,
I did a little preliminary investigation before disconnecting Marigard from her parents. I'm not finding anything that tells me what's right. Do you have a good source?
A quick internet search shows that different people variously claim she was daughter of Ranulph (Ralph) of Essex, of Earl Godwin, and of Godwin's son Leofwine.
Charles Cawley at MedLands seems to have nothing.
I found one mention of a Marigard at soc.genealogy.medieval that says Godwin's daughter of that name is unaccounted for.

It might be a good idea to disconnect her from Leofwine if that information can't be supported, but I'm not sure whether we have enough information to firmly connect her to anyone else.
I think you're right, this suggests she is connected to Harold ii's family

I'm suspicious. There wouldn't have been a duke (or earl) of Essex at this date.

As I poke through internet searches the impression I'm getting is that Marigard was daughter of Godwin. There seems to be no evidence about her life, but someone somewhere has suggested that she married Dunning de Lathom.
