Hi Ron,
Good to hear from you. Well Matthew Armstrong b. 1819
was one of the sons of James Armstrong and Elizabeth Liddle.
James and Elizabeth were married in Glasgow in 1810, 
his occupation is listed as a soldier, the regiment number 
is hard to work out due to the handwriting.
James and Elizabeth had 5 sons James, John, Matthew, 
Matthew and Hugh. Sadly the first Matthew died in infancy 
and the second was born in 1819.
I have details on the Liddle side of the family, but sadly 
information comes to an end with James, since I cannot find 
any record of his death certificate.
I hope you have better luck 

Regards,
Richard
