John Roberts - John Roberts 1699

This John Roberts is incorrect. It needs to be revised. John Roberts born 1699 to John and Joan Periam of Paul. They then had Benjamin 1701, Catherine 1703 and William 1706 we believe. John had married Cattran Roch/ Rock at Paul Parish in 1690, one child Katerin died 1691, then they had Mary 1692, but Cattran died in 1694. John remarried Joan born 1664 from Gwennap in 1697 in a double wedding with her sister Elzabeth to John Roskcrow. Joan was 33.
John born 1699 and Leah Roberts nee Harry married 1721 at Paul Parish and had Ann, Abraham my relation, John who died young. Catherine, John born 1731, Frances born 1734 who married John Tremethack, James and Leah who married Paul Periam. Will,of John Roberts 1775 will confirm these children. Also,refer to Will of John Roberts 1735/6. They were both Blacksmiths. Wills open.
I have yet to find the baptism of John who died in 1735 if anyone can help. Diane from Western Australia
