RE: Elftred 'the Englishman' - ancestor of the Curwens

Dear Todd

Upon reflection, I note that the original post I am asking about did give a
reference to a webpage which at least reminds me more clearly about what the
claim was which I am asking about the basis of:

"The sons of Bethoc and Crinan were King Duncan I of Albany (killed in
1040), whose descendants bore arms of the colors red on gold; and Maldred,

note that probably 80% of shields had gold or silver, and probably 75%
had red or blue, so this in not saying much. In this case, it was a red
lion and some frill on a gold shield.

Maldred, son of Crinan (assumed to be the same Crinan who married
Bethoc, although this is not directly attested) did not "rule"
anything.

Ruler of Cumbria, who married the daughter of the Earl of Beornicia, and

whose descendants bore arms of the colors red on silver (white). From

I don't know what family they have in mind here, so I can't identify
the arms.

Maldred's son Gospatric, Earl of Beornicia (which passed from English to
Scottish control during his tenture, and whose original Saxon House is
represented in the male line by the Swintons of that Ilk), are descended the
families of Dunbar, Dundas and Moncreiff."

So is it being claimed that Swintons, Dunbar, Dundas and Moncreiff had/have
arms like those of the de Lancasters? (Argent, two bars and a canton gules.)

taf...

No. It is being claimed that they both had something red on a metal
background, which is probably the case for, say, 10-20% of all arms.

A quick browse around the internet finds only one of these arms even had the
right colour pattern? See for example
