Roberts family in Rock

[msb]

Please can anyone help?
My 3 x great grandfather, Richard Roberts and his wife Eleanor, had at least two children christened in Rock, Worcestershire; Richard junior 2nd August 1799 and Cordelia 8th July 1800.
Does anyone know anything about this family or where to find any information? I would like to know about Richard and Eleanor's marriage and whether they had any other children christened in the area.
I have found another son Henry christened in Clifton Campville, Staffordshire in January 1803, so presumably they had moved away from Rock, but I'm still missing at least one other child, possibly Sarah, who later marries a Mr White.
Thankyou for any info you can provide!
