all events
1601 first record in Colne, Lancashire
Poulson in 1750's in Liverpool - a Sailor
Burial: 3 Feb 1763 St Peter, Liverpool, Lancashire, England
Paul Poulson - Son of Nich. Poulson
Occupation: Sailor
Baptism: 14 Aug 1773 St Peter, Liverpool, Lancashire, England
Elizabeth Poulson - Daughter of Nicholas Poulson
Born: 29 Jul 1773
Occupation: Mariner
so it looks like Nicholas Poulson was the first in Liverpool - I would have thought Poulson comes from Paulson - son of Paul
Marriage: 18 Nov 1753 St Peter, Liverpool, Lancashire, England
Paul Paulson - Sailr.
Cath. Sinclair - Spinster
also a sailor - let me check om Poulson surname
it would appear you are correct - the earliest Poulson I can find is this tree and it is from Skanderborg,Denmark
starts 1635
