The early history of Pantyrhwch is not known, it is situated on the edge of lands that belonged to a medieval monastic grange that belonged to Llanllyr.
The earliest occupier of Pantyrhwch found to date was Evan David a "cottager" whose death was recorded in the Lampeter parish book on 24 December 1699.
Pantyrhwch is shown on Thomas Hughes' Llysvane estate map of 1802.
It is subsequently recorded as part of the Neuadd Fawr estate owned by Thomas Hugh Rice Hughes who died in 1902 leaving his estate, which included Pantyrhwch to his wife Alice Mabel Hughes who died in 1930.
Census research showed that in 1841 the tenants of Pantyrhwch were Thomas Lewis, farmer, 55 yrs old (born around 1786), Elizabeth Lewis, wife 40 yrs old and Mary Williams 10 yrs old. The census records show two properties at Pantyrhwch these are confirmed on various maps. Living at the second dwelling were William Williams, farm labourer, 30 yrs old born in Llanllwni around 1811 and Sarah Williams his wife, 25 yrs old.
The 1851 Census records Thomas Lewis a small farmer, 72 yrs old still living in Pantyrhwch with his wife Elizabeth Lewis, 55 yrs old and John Jones a lodger, 11 yrs old. William Williams Agricultural labourer 39 yrs old and his wife Sarah, 32 yrs old were still living at the second dwelling together with their two daughters Elizabeth Williams 10 yrs old and Sarah Williams 5 yrs old.
The Census of 1861 show that Thomas Lewis must have died as his wife Elizabeth Lewis 67 yrs old is recorded as the farmer of the 8 acres comprising Pantyrhwch. Living with her were Elizabeth Davies dairymaid 35 yrs old and Esther Thomas 4 months old. Still living at the second dwelling were William Williams agricultural labourer 49 yrs old, his wife Sarah 42 yrs old and their daughter Sarah, scholar 14 yrs old.
The 1871 Census Elizabeth Davies, 41 yrs old (born around 1832) as the farmer of Pantyrhwch comprising 6 acres and living with her was her daughter Esther Thomas 10 yrs old. This suggest that Elizabeth Lewis must have died and Elizabeth Davies who was the dairy maid took over the tenancy....why her daughter has a different surname and why there is no mention of a husband is unclear. William Williams, labourer, 58 yrs old is still living at the second dwelling with his wife Sarah 52 yrs old and their 5 yr old grandson David Williams.
The Census of 1881 has Elizabeth Davies, farmer, 49 yrs old still living at Pantyrhwch comprising 9 acres together with her daughter Esther Thomas 20 yrs old (born around 1861) and Mary Jones a lodger unable to work, 47 yrs old (born around 1834).
