On 16 Apr 1765 Archibald Douglas married Miss Hake, in Honiton, England.
They had a son, William Archibald Douglas who went missing on Madeira Island along with a fortune in gold dust, and was presumed killed. They also had three daughters, Susannah, Isabella and Charlotte.

Archibald had a brother in law, Samuel Pett.

On 8 Jun 1761, Susanna, daughter of Samuel Hake, married Samuel Pett. Susanna may have had two brothers, John b1748 and Cotton, b1750. Their father was a clothier.

Is this the same Samuel Pett? Did he marry secondly Miss Douglas?

Who were Archibald's parents?

Can anyone add to this?
