I don’t think this is going to lead to any connection the the Neilsens who are Powys descendants.
The birth of Thomas is the only Nielsen birth on record in FindMyPast’s World records with a mother’s maiden name of Groth.
Ancestry has 5 Nielsen-Groth births in addition to Thomas’s from 1957 to 1977, all these 5 being in the USA.
