Mary St. Aubyn

Mary Grenville, married firstly Richard Bluett (1479-c.1523) of Holcombe Rogus in Devon and Cothay Manor, which he rebuilt, in Somerset. His monumental brass exists in St Nicholas' Church in Kittisford, Somerset; secondly to Thomas St Aubyn.

Question, Richard Bluet died in 1523 and Mary Grenville married Thomas St Aubyn after he died and yet the birthdates for the children from second marriage are before 1523 in some cases, how does that match up?
