Who was the legal grandson of the Earl of Merica?
Ælfgar, Earl of Mercia Ælfgar (died c. 1060) was the son of Leofric, Earl of Mercia, by his famous mother Godgifu (Lady Godiva). He succeeded to his father's title and responsibilities on the latter's death in 1057. He gained the additional title of Earl of East Anglia, but also was exiled for a time. Through the first marriage of his daughter he would become father-in-law of the Welsh king Gruffydd ap Llywelyn; a few years after his death, his daughter would become a widow and marry English King Harold.
Henry Howard, 5th Earl of Suffolk Henry Howard, 5th Earl of Suffolk (18 July 1627 – 10 December 1709) was the youngest son of Theophilus Howard, 2nd Earl of Suffolk, but inherited the title, because none of his brothers left surviving sons.
