Brokenshire Family of Padstow

My great great grandfather James Elias Langdon Brokenshire was a harbour pilot in Padstow. His son William, my great grandfather, was a shipwright and moved from Padstow to work in HM Dockyards, Plymouth. My grandmother Elizabeth Jane was born in Francis Street in 1869. She married John Williams of Madron in Cornwall and they moved to Cwmaman in South wales in about 1900. I am researching this family.
