The Nicholas Snowe who was baptized 25 Jan 1599/1600 was buried 3 days later on 28 January. He could very well be the son of a Nicholas Snow and Elizabeth Rowlles but he isn't the husband of Constance Hopkins. See the Spring 2013 edition of MAYFLOWER DESCENDANT (thanks Margaret) for Caleb Johnson's story on that.
See the free Parish transcription showing the baptism and burial of that Nicholas Snowe
