Nice job.
Ref Neal's query:
Does the heraldry relate to anything specific?
Sven: I don't know whether you just came up with the scheme or found a reference?
It's not easy to see whether it's red chevrons (technically chevronells) on white (argent, three chevronells gules) or white on red (gules, three chevronells argent) but either way, I had a quick looksee at the minefield that is online genealogy and heraldry and came up with some interesting possibilities (and many highly dubious ones).
However, one must forget the idea that a particular blazon was unique to one family... or that all of a family wore the same arms (especially as the various branches multiplied). To illustrate this, here are some examples:
Amongst the best is the French de Plessis family (from a branch of ... as per today's South African rugby players)... this is Cardinal Richelieu's:
The C14th Surrey/Willement Rolls offer various versions, including de Langeton (differenced with a blue label: both original and cleaned up versions are shown) , Baude (white on red), and Sakevill (differenced by a field of ermine).

Other sources include de Watevile (note the differences), Barringtone and de Vere (from the C14th Parliamentary Roll)

And from Ireland, France and Germany and Belgium (Flemish): Bladen, de Bassompierre and the town of Menin (Menyn):
Here are some more (some with a gold/or .. ie yellow field) from a French book of arms (I think the Egmond one with multiple chevrons is 'chevronelly of five argent (or?) and gules'):

However, my favourite (for the irony of the name) is the Anglo/Scottish Meek family:
So... you pays yer money and takes yer choice
