Hi,
The 1901 census shows this family at Blackhall, Llandyssil - Edward Owen (28), Farmer b. Mochdre , his wife Sarah A Owen (26), b. Forden and 2 children, Edwin A (or R?) (3) and William R (2).
The likelihood, therefore, is that the Forden marriage identified by Carole is the right one - Qtr Dec 1896 Edward Owen & Sarah Ann Evans Forden 11b/359.
The marriage certificate will give you more information to validate names of their fathers.
It is probable that Edward is the son of David & Jane Owen, who in the 1871 census were at The Mill, Escaergeiliog, Mochdre. David (38) b. Kerry is a Miller, wife Jane, also born in Kerry is aged 36. They have 4 children, Richard (11), Pryce (7), Herbert (4) and Mary Ann (1).
By 1881, David (48) was widowed and now described as an 'Ag. Lab.'. Mary Ann (11) was still at home together with Edward (

.
David was still at The Mill, on his own, in 1891 and 1901.
If you need any other census look-ups for this family, please ask.
Good luck
Stan
