Hi,
Could anyone trace a marriage between Thomas Ruddock & Mary Ellis

Some of their children were baptised in Dickleburgh. Elizabeth & Maria 16th June 1799 & Thomas 13th June 1802. I am thinking it would be c1796-1799 in that area of Norfolk but I am not ruling anything out at this stage.
I am really struggling with this part of my tree as the parish records for Dickleburgh show children baptised in the period 1792-1812, some to:
a) Thomas Ruddock & Mary Allen
b) Thomas Ruddock & Mary Ellis
c) Thomas Ruddock & Mary (unknown)
I am trying to work out if there is one Thomas with two wives named Mary or two Thomas Ruddocks each with there own wife called Mary.
I have traced the marriage of Thomas Ruddock to Mary Allen in Syleham, Suffolk in 1791. It states that Thomas is from Dickleburgh so I am happy this is correct.
I now need to untangle the rest. I think I need either...

a) the wedding of Thomas and Mary Ellis to see if he is listed as a widower etc
b) the death of Mary Allen c1796 which would help to prove the 2 wives named Mary theory.
c) alternatively proof of 2 baptisms for Thomas Ruddock's in Dickleburgh area in same period.
But I can't seem to find anything

Any light anyone could shed on this would be most appreciated,
Many Thanks,
Sarah
P.S Spelling of Ruddock can vary a lot ruddock/rudduck/ rudoc etc
