Picture and below description do not match. Each came from separate resources. I'm not sure which is more accurate.

"At another website, I found the silver shield with four roses described as the GERMAN Williams Coal of Arms. At least 2 other websites verified the picture you had (Welsh Williams), but one used colors of red lion, yellow shield and blue bar above the lion." (Info from Ben Williams. Thanks Ben !!)

The Shield is: A silver shield displaying four roses

The Crest is: A rose

The motto is: None
