Early records of the name mention William Siby, 1227 County Yorkshire Warin de Seby, was documented in the year 1230 in the County of Yorkshire. Agnes Seeby of Yorkshire, was listed in the Yorkshire Poll Tax of 1379. In many parts of central and western Europe, hereditary surnames began to become fixed at around the 12th century, and have developed and changed slowly over the years. As society became more complex, and such matters as the management of tenure, and in particular the collection of taxes were delegated to special functionaries, it became imperative to distinguish a more complex system of nomenclature to differentiate one individual from another.
Samuel Seabury (1873-1958) was an American jurist, born in New York City and educated at the New York Law School. He was elected a justice of the New York Supreme Court in 1906, and elected a judge of the New York Court of Appeals in 1914. In 1930, he was elected to investigate the government of New York City. The disclosures of scandals uncovered led to the resignation of the Mayor. Seabury was elected president of the New York Law Institute in 1937. At first the coat of arms was a practical matter which served a function on the battlefield and in tournaments. With his helmet covering his face, and armour encasing the knight from head to foot, the only means of identification for his followers, was the insignia painted on his shield, and embroidered on his surcoat, the draped and flowing garment worn over the armour. Translation of the arms: Sable (black) denotes Constancy. Argent (white) signifies Peace and Sincerity. Or (gold) denotes Generosity.
The lion is the noblest of all wild beasts which is made to be the emblem of strength and valour, and is on that account the most frequently borne in Coat-Armour.
