Falconbridge - Prestonpans 1723

[myrtlebank]

Can someone please help me?  Am looking for a marriage - John Falconbridge (b around 1723) to Jean Boyd around 1755, Prestonpans.  Son William born 1755. Apart from the marriage of Samuel Falconbridge to Mary Brown in 1786 I am unable to find any more info on this family.

A Samuel Falconbridge was involved with Roebuck's vitriol works in Prestonpans and was dismissed in 1749 (apparently then went to Shropshire).

This family were nonconformists.

Any suggestions where to obtain info prior to 1723 greatly appreciated.

A particular name I am searching for would be Alexander b around 1760.  Other names in the family could be Thomas, John, James.

Thank you, Valerie
