Moving to the LDS Pilot Site for the Irish GRO birth indexes you can find references to order certificates for Valantine and Sarah

Sarah Sefton, , Birth, Lurgan District, 1869, Vol 16, Page 750
This is the information you require to order certificates from the GRO in Belfast for £6 each (but don’t say you got the information from the LDS website – it only causes problems)

[Nothing found for Sarah again]
I had a look on the sites mentioned for marriages for Joseph Finlay or Valentine Sefton senior, but no likely matches came up. Civil registration only began in 1845, so church records would be your best bet.
There seem to be a lot of Seftons in the Banbridge/Lurgan area (including 4 Valentines with deaths registered in the period 1864 to 1900) so best to look for church records in that area.
