I am looking for a possible marriage between Catherine Sullivan and ? Thorrson in Polk County between 1876- 1880. Does Crookston county records have marriage records that early? If so, is there anyone in Crookston who would be willing to do a lookup for me? Catherine Sullivan came to East Grand Forks in 1876 and there is a Catherine Thorrson (correct age) living with her uncle's family in the 1880 census. I am trying to establish if this is one and the same person. Thanks, Rita
