I've been going back and having a look at some of the older queries that I had noted in the past with fresh eeyes and new discoveries that have been made since then.
It looks as if back in 2012 I purchased a marriage certificate between a Thomas Place and an Elizabeth Nightingale (nee Moorby), likely thinkng that it was Thomas Place, son of Robert Place, born 1827 in Blackburn, Lancashire, England. But on receiving it, I discovered that the father of Thomas Place in the marriage certificate is Joseph Place:
So, the question was, was that the wrong information on the marriage record (which I have seen before), or were there two different Thomas Places, born around the same time in the same place.
As for the Thomas Place, son of Robert Place, the only records that I have been able to definitely verify as being his are baptism records and the 1841 census. I did some digging, however, and managed to find records of the Thomas Place, son of Joseph Place in a baptism record.
I have also found both of them in 1841 census records. So, it would appear that we are looking at two different individuals and the marriage record is from a different Thomas Place.
So, mystery solved, but this raises the question of what became of Thomas Place, son of Robert Place? I don't have any definite records for him beyond his appearance in the 1841 census. Other trees on Ancestry have him dying in 1866 and some have him marrying a Sarah Ramsbottom in 1870. Not sure if either of them are true (they obviously both can't be true) but that is a mystery for another day.
