This is the only entry I can find that would meet your criteria. It means that Margaret married under age so it may worthwhile looking at the Parish Register.

1851, Michael, district 3, schedule 10, Little London
William Corlett, head married, 42, farming 72 acres, Michael
Margaret, wife, maried, 44, German
William, son, 16, Michael
John, son, 14, Michael
Margaret Ann, daughter, 11, Michael
Ann Jane, daughter, 5, Michael
Catherine Mary, daugher, 2, Michael.

The family appears to hit hard times. In 1861 William is listed as an agricultural labourer. He and Margaret and son William are still living in Michael.

All the other children are listed as servants with various families except for Margaret Ann who cannot be identified - which would agree with marriage and emigration.
