Looking for John Barnett and Hephzibar Barker London
I am trying to find where my GGGG Grandfather John barnett born c 1770 was born. He married Hephzibar Barker in LOndon at St. Nicholas Cole Abbey on 14/2/1791. They had 9 children Susannah b 1791, Ebenezer 1794, Josiah B 1796, George Caleb b 1800, John Barker b 1801, Hephzibar b 1803, Samuel b 1805, Jane b 1807 and Samuel b 1811.
I thought maybe he could be Jewish. Any help would be gratefully appreciated. Thank you
