Prices of Abertillery - help sought!

[HistorySeeker]

I am searching for my grandfather's family.  His parents were Joseph Price (aged 25 in 1901 census) and Sarah (nee Williams, aged 23).  Joseph was born in Abertillery, Monmouthshire and Sarah in Nantyglo, Monmouthshire.

In 1901 they are living in the Underhouses in Princess Street, Abertillery with their eldest son Clifford L (possibly Lewis) aged 10 months.

They went on to have 8 more children Thomas, Phyllis, Clarice, Leslie, Albert, Leena, Olive and Nancy.

In 1909 on the birth of my grandfather (Leslie) they are still in Princess Street.  After that at some point the family broke up, Clifford and Thomas to Nottinghamshire (we think), Phyllis & Clarice went into service and Leslie, Albert and Leena were sent to the Cottage Homes in Tredegar.

That is the sum total of my info - does anyone here know anything about this family?

Thanks
