Sorry, can't find a marriage in Oxfordshire for Edward House & Ann.
BUT......if you check the 1841 census, there is a tantalising entry.
Clebard(Edward) Howse b.1781. Berkshire.
Jane Howse b.1791. Berkshire.
Charles House b.1796. Berkshire.
Mary Howse b.1826. Berkshire.
Stephen Howse b.1827. Berkshire.
Civil Parish - Appleton
Hundred - Ock.
R/D-Abingdon
S/R/D-Kingston Bagpuise.
The original image is very feint.
Maybe Berkshire holds a marriage.

Steve.
