There are a LOT of Trigg's. The baptism you have found is from another line, it is for Richard Trigg son of Richard Trigg & Mary Risley. Richard Trigg & Mary Risley had 9 children including Benjamin who married Priscilla Welch, who is the subject of another thread seeking to establish which Benjamin was which.

As Slowhands has indicated it is thought that Benjamin Trigg who was the father of "your" Thomas Trigg who married Sophia Jane Baldwin was the son of Richard Trigg & Elizabeth Jenkins. Unfortunately with the limited information recorded at this time, it is not possible to be 100% sure and judgements have to be made based upon the information that is available.
