Pengroesoped Cottages were built about 1851 by William Williams in the garden of the Old Thatch Cottage whilst he was in ownership.

The census of 1861 says Elizabeth Fisher is in occupation with her son Edwin, they had previously lived at Goytre Wharf.

By 1867 the new owner of the Cottages was Richard Drinkwater, living there was Robert Davies who had moved to Pantglas Mill house before the 1871 census as the census of that year showed George Watkins a 34 year old agricultural labourer born in Hereford, his wife Mary Ann 25 born in Llanover upper and Heanna 3 living at number 1.

Living at number 1 on the 1881 census is Amos Jones, a 41 year old agricultural labourer born in Llandenny, his wife Martha is 43 from Glascoed, their children are Henry 8 and Elsie 2 both born in Goytre.

This had changed again by 1901 when 36 year old Isaac Heaven, a carter at the mill, and his family took occupation. Isaac was born in Llanover, his wife Frances 35  from Llanvihangel Gobion, their daughter Louise 6 was born in Glamorgan.

By 1911,  50 year old widow Elizabeth Evans and her 48 year old brother Phillip Jenkins and Elizabeth’s 19 year old daughter Louise a dressmaker had become the new occupiers of number 1. Elizabeth and Phillip were born in Goytre, Louise in Pontypool.

Louise had left the cottage by the 1921 census but Elizabeth and her brother Phillip were still living there at the time of a tragic accident when Phillip was killed, the report is under inquests in March 1927.
