I found the actual records in FamilySearch that you just mentioned in the profile. I put in the actual citations in the profile. I also found the birth record in FamilySearch and put that in the profile too.
While this is not completely conclusive, I'm tending to think this person is female, based on these things:
- The first name is consistently spelled "Jessie". This is more often than not, a feminine form of the name. Typically, males are spelled as "Jesse". Although I have a counter-example in my own family.
- I've seen Census records get the gender wrong on children quite often. But rarely do they get the gender wrong on adults. The 1940 Census shows Jessie as female, at age 19.
Based on those things alone, I would recommend Female. Is it completely conclusive? No, not yet. It would be good to find a marriage record, or death record. I haven't found either of those yet.
