Gilbert was born at
Sempringham, near
Bourne in Lincolnshire, the son of Jocelin, an
Anglo-Norman lord of the manor, and an unnamed Anglo-Saxon mother. He had a brother, Roger, and a sister, Agnes. Unusually for that period, his father actively prevented his son from becoming a knight, instead sending him to France, probably the
University of Paris but possibly under
Anselm of Laon, to study theology. Some physical deformity may have made him unfit for military service, making an ecclesiastical career the best option. When he returned in 1120 he became a clerk in the household of
Robert Bloet,
Bishop of Lincoln, started a school for boys and girls (the existing primary school at
Pointon is still named after him) and was ordained by Robert's successor,
Alexander. Offered the
archdeaconry of Lincoln, he refused, saying that he knew no surer way to perdition. In the period 1115-1123 he was given both the vacant churches of Sempringham and
West Torrington, near
Wragby, by his father, Jocelin. In 1129 he became the Vicar of both St Andrew's,
Sempringham and St Mary's,
West Torrington having been instituted by Robert Bloet, Bishop of Lincoln. "Gilbert was a lover of truth and justice, chastity and sobriety, and a diligent cultivator of the other virtues: wherefore he was revered and praised by all and obtained their favour and regard. Even Jocelin now rejoiced in the goodness of his son, he began to cherish him with fatherly affection, and ministered to his needs out of his own riches. Gilbert would be in his late twenties when his father presented him to the vacant churches of Sempringham and West Torrington, which he had built on his own demesne 'in the custom of his country' " ==The Gilbertines==
