Hello, I'm wondering if you are interested in the family of John White of Tywardreath? I located a marriage record for John to Susan Penrose/Penvose June 16, 1846. I believe Susan may have been a sister to my ancestor, John Penvose who died in Tywardreath in 1866. The marriage record states her father was John, John White's father is listed as Thomas White, a miner. I haven't researched this line further as of yet. I believed the surname was Penrose, but all of John's children used the Penvose spelling in the US, as did his son, Edward, who settled in Barnsley, Yorkshire.
