Hi there Yes Christian is the person mentioned in the 1851 & 1861 UK Census Middlesex district.
Unfortunately I have absolutely no idea of birth, month, year at this stage on both Father & son.
Peter is not found at all other than when he marries Ellen Fulton 7 May 1848 Liverpool & after Ellen dies remarries Mary Rickarby 20.2.1871 Birkenhead, Cheshire UK.
I really appreciate you listing these Thomsen folk as possibilities - please can you give me an idea in English their occupations & country of birth?I don't quite understand the Danish wording. Very many thanks in advance MaryBeth
