Yes, I've found exactly the same information. Perhaps, and it's only a perhaps, Simeon felt that he had to give a father's name on his second marriage and gave the name Lewis. I can't see any evidence that a Lewis Sunderland ever existed (yet!!!!).
Unfortunately, even if we find the marriage between Simeon and Susan, it is by no means certain that it will solve the mystery of Simeon's parentage - pre-1837 marriages do not contain parents' names, so the only hope would be the name of a witness

But a marriage in any form would be a bonus

It would be wonderful to find the marriage between Simeon and Susan, but chances are that it would have been conducted in HER parish - protocol played a fairly dominant part in those far-off days, and it was more usual for the marriage to take place in the bride's parish!!
As of this moment there is nothing to see BUT "they will be found when they want to be found" is my motto, and I've been proved correct on a number of occasions
