Hi seth2
Looking at your info slightly confused
the 1851 census 2488/278/8
Samuel Parry father-in-law b 1771 llangamach pauper
Is this the same Samuel on
1841 census 1365/ 10/11 /15
Builth
Samuel Parry b 1771 brecknockshire ag lab
Gwenlean Parry b 1773 Brecknockshire
I see this marriage
Samuel Parry =m= Gwenthlean Powell
14th May 1821 Builth
If this is the correct samuel is Gwenlean his second marriage?
I don't see the birth of Mary
I note that on the 1841 census 1365/ 16/5 /5
Cevenbeth Llanganlen treflis
Edward Powell b 1796 Brec ag lab
MARY B 1801 Not Born CountyRose b 1832
Samuel b 1836
Mary B 1838
William B 1836
This looks like the same family as 1851

Not sure this helps
cheers cardiff
