Can you describe, or attach a picture of, the Arms you say were "awarded to the Garsed family in 1066 after the Battle of Hastings and the loss of 3 sons". One thing is certain, although the Arms may exist, they were not awarded in 1066 as Coats of Arms did not exist at that time, only coming in to use in the mid/late 1100s, and then not "awarded", just adopted ("assumed") by the gentry. That said, if you can describe the Arms we may be able to establish if there is a connection to the Yorkshire Garseds.
