Shelley from Staffordshire Originally

Hello
I'm researching my husband's SHELLEY (sometimes spelt SHELLY) family, who originated in Staffordshire (Stone, Tutbury, Rolleston areas), then spread out to Cheshire and Lancashire, and overseas.
I have Robert Shelley, a coal merchant, born about 1781 in Tutbury, Staffordshire, to parents Joseph and Mary - Robert married Sarah PYATT (sometimes spelt PYOT)in 1816 in Sandon, Staffordshire.

Best wishes
Rachel
