i've been looking into Illegitimate children of British King, and i found something, a ton of them have names that start with Fitz
Henry FitzJames son of King James II
James FitzJames son of King James II
Charles FitzRoy son of King Charles II
Adolphus FitzClarence son of King William IV
Frederick FitzClarence son of King William IV
Henrietta FitzJames daughter of King James II
Adam FitzRoy son of King Edward II
Matilda FitzRoy daughter of King Henry I
Richard FitzRoy son of King John I
Barbara FitzRoy son of Charles II
Henry FitzRoy son of King Charles II
Henry FitzRoy son of King Henry I
George FitzClarence son of King William IV
George FitzRoy son of King Charles II
Charles FitzCharles son of King Charles II
Henry FitzRoy son of King Henry VIII
so what gives? what does Fitz mean? and i get why FitzCharles for the sons of Charles and FitzJames for the kids of James, and FitzClarence for kids of the Duke of Clarence, but what is FitzRoy about?
