Hello Julie, after checking the '92 IGI LIGHT files - I have just one GOUGH, but probably not the same as yours.
I didn't find any GOUGHs listed in the birth records but after looking in the LIGHT marriages I found;
Elizabeth GOUGH married Edwin Light, 01 APR 1865 at Holy Trinity, Clapham, Surrey.
Batch #: M058452, Source Call #: 307720,307721
In the birth records I found;
Ann Light born 20 DEC 1840 at West Lavington, Wiltshire; parents; James Light & Jane
George Light born 1845, Woodfalls, Wiltshire; parents; George Light & Selina Moody
George Light & Selina Moody - married 23 Oct 1832, St Laurence, Downton, Wiltshire
Elizabeth Light married William Ralph, 25 May 1799, Grittleton. Wiltshire
