Hi Maec
Yes it is the Marmion family.
The original senior 3 lines of the family (Tamworth, Winteringham & Torrington) are all listed as having the original arms they had back in France.
"vair a fess gu"
According to Charles Ferrers Palmer, who has probably researched the family more than anyone else, a line eminating from the sixth son of the senior line, settled at Galby Leics. In Galby church there are 2 coats of arms identified as being Marmion ones listed in Nicholls History of Leicestershire:-
1 - "vair, a fess gules, fretty or"
2 - gules, a lion argent rampant, crowned or
and interestingly an Everingham one quartered with another
3 - Quarterly, 1 & 4 gules, a lion argent rampant, crowned or Everingham; 2 & 3 per pale and a bend...
At first I thought Nicholls must have confused the arms of the Marmion and the Everingham families but Burkes General Armory also list the Marmions using the lion rampant design in addition to their original simple "vair a fess gu".
Confusing...
