Looks like more than one family.
You haven't given exact dates of birth or addresses from the certs, but there is this family in Aberdare in 1861 which could be the one for which you have the certs
Gloucester Street, Aberdare RG9/4066 folio 96 pg 11
Thomas Francis head mar 25 mason b. Pembs, Wiston
Ann wife 25 b. Glam, Swansea
Mary dau 3 b. Aberdare
The 1861 for the other family
65 Ynislwyd St, Aberdare RG9/4066 folio 60 pg 21
Thomas Francis head mar 27 coal miner b. Glam, Penefail
Hanna wife 26 b. Carms, Whitland
Ann dau 2 b. Glam, Aberdare
+ 2 boarders
How sure are you that your Hannah was the widow of a Thomas Francis, rather than another Mr Francis?
