From the information you have for #1, it was born 31 Dec 1922, it is an UNNAMED INFANT and you do not know the sex of the child.It was the child of Benjamin R Senter.I think it was born dead and buried.A death certificate was not filed with the state.You might try the county for the death certificate.
There are mistakes in the records for #2.He was born Roland Senter Jr. which means his name is Benjamin Roland Senter Jr.I think he was born 23 Nov 1926 and died 19 Dec 1926.How he got into the 1927 records is unknown to me.
In either case, neither is in the 1930 census with the family so they are both deceased.
Not all records were sent to the state in that time period.I would check with the county for clarity.You might also check the cemetery for burial records or tombstones.
Sorry, mistakes happen and sometimes they can't be figured out with limited info.
