Whilst there are a variety of other children of Robert and Elizabeth Cook christened in the years after 1815 in Welton le Marsh, I can't see a Thomas Cook ch. in 1815 that would fit. The first child of Robert and Elizabeth that shows is christened in 1816.
IGI only have 2 Thomas Cooks being christened in 1815 in Lincolnshire and those are to a William and Elizabeth and the other to just an Elizabeth Cook.
