Hello!I dont have a John Heselden listed in my genealogy register at this time, however that does not mean there isnt a connection.It would be interested to find out if there is a connection.The Heseldens that I have are:
Francis Heselden (unknown birth or death)
Mathew Heselden (b. 1742) James Heselden (b. 1749) Mary Heselden (b. 1751)
Is it possible that your John was the son of Francis?Maybe my source didnt know of another son.Or could John be the brother of Francis?We will have to compare notes and dates to see if there is a connection.Please feel free to email me at firstname.lastname@example.org.
