You'll need to say more - few people today will recognize relatives of that era.
I found a Marinus Nielsen age 22 immigrating in 1916.
This makes him born about 1894.
He's a machinist.
Father is Adolph Christensen of Vizzgarden???
Place of birth Knubholmen????
Very hard to read the place names. Much more information on him on the manifest, but it is scribbled such that it is very hard to read.
Seneca, Kossuth, Iowa
Marinus Nielsen 46 born about 1894 in Denmark, farmer
Alma Nielsen 29 born about 1911 in North Dakota
May Nielsen 11 born about 1929 in Iowa
Merina Nielsen 8 born about 1932 in Iowa
Is this your Marinus?
