No, I don't think that is the one.
I have -
1840 Census -5- Vinmill, Dymock - with John & Mary Minchin-not born county
1851 Census -14-Lodger - Nomansland - ag lab - born Midloe, Cambridgeshire
1861 Census -24-Head - U Castle Tump - ag lab - (listed Frederick),born London -Mary Minchin boarder

possible brother - Thomas, b 1839 - Dymock - 1851 boarding with Mary Minchin, Dymock Village - possible baptism 24/06/1838 - Dymock - Vell Mill - base born son of Elizabeth.

It is quite confusing but John & Mary Minchin keep popping up, I wonder if they are perhaps the Grandparents.
