I'm trying to find more information about Sydney Jones born about 1852 in Middlesex,her father was Evan Jones born Llanengan to John and Catherine Jones,I do not have Sydney's mother's name,she must have died when Sydney was young and she came to live with her aunt Laura to Bryn Derw, Llanberis,I have found her in the 1861 census living at Bryn Derw but cannot find her before or after that date,could someone please help me?
