Need help in sequencing the BULL family Coat of Arms. During my research, I have found at least 10 different styles. Some are the same but with different face shields, plumage, and 'bull' figures. Some are yellow, some green, some blue. Which CoA was first, what is the next in line, and so forth. I have searched as far as the 12th Century up to the 18th Century. Different CoA are scattered throughout the lineage. Any help to put these CoA in sequence is appreciated. Most online sources just want to sell you a CoA wood plaque. I am having little luck in finding the correct source. Thanks.
