Hello
I have just found this and as another descendant of Thomas & Gertrude am fascinated.
Thanks to the famous family tree, the contents of two boxes of papers in the possession of a cousin & many hours in the Cornwall Record Office (CRO) I have gathered a fair amount of information about the family and in particular the Crantock line & Johns connections.
The picture of Penpol caught my eye. I know for certain that Joseph leased the farm as sub tenant to Thomas Rickard who had inherited the tenancy from Thomas Symons in about 1717. The lease was for five and a half years and suggests that Joseph was already in possession. Leases were renewed until November 1801 when Joseph's grandson, William son of Thomas and Ann purchased it. My great grandfather, William, son of Silas Hiscutt Martyn and Harriet nee Johns inherited the property from bachelor uncle William in 1883 and later in that decade had the makeover carried out that resulted in the house shown in the photograph. I was taken there in 1951 when my father's cousin, son of his aunt, owned it. The last William Martyn and male heir of that line, died, shortly before his 22nd birthday in 1899.
Also there was mention of the date of the Ann Hiscutt /John Christian marriage at Looe. Do you know which church?
Best wishes
