Regarding your request for information on the Lloyd family, on the 1911 census they were still living at 16 Taff Street, Treherbert.On the census the following persons are listed:
Sarah Lloyd, age 42, born Limerick, listed as a Widow.
John Lloyd, age 22, born Limerick, listed as a Railway Stoker.
Robert Lloyd, age 21, born Stonecliffe, England, listed as a Colliery Worker.
George Lloyd, age 19, born Limerick, listed as a Blacksmith Striker.
Lizzie Lloyd, age 19, born Treherbert, Daughter in law of Sarah.
Florence Lloyd, age 12, Burma/India resident.
Elsie Loyd, age 9, born Treherbert.
Harold Lloyd, born 1911 Pentre. The census was taken on the 2nd April that year so you can assume he was born sometime in the previous 3 months. I hope this is of help.
