Hello

you would have to confirm this with parish records:

THOMAS VERNON
Spouse: SARAH ELLSON
Marriage: 13 MAR 1820 Chester, Saint Oswald, Northumberland
but seems a little early for the 1st born not to be till 1830

+

THOMAS VERNON
Birth: 28 APR 1808
Christening: 06 MAY 1808 Stoke Upon Trent, Stafford
Parents: JOHN & ELLEN

If you obtain young John's birth certificate, it will show mums maiden name so then a marriage can be found correctly
