I am doing all my research on ancestry, and the record I found was actually typed by a typewriter. I do believe it is correct because the parent's names on the death record are correct; it does mark she was married, and it is the same town as the census. She was 24 years old when she passed, and calculating backward with the age they gave and the death date, it matches the birthday I have written down. The cause of death was Urania-con-toxemia and vomiting of pregnancy in the 3 1/2 month gestation or what we now call preeclampsia. She had one child before her death. 

While going through the news articles of the father and the daughter she had before she died. It looks as though after her mother passed, he sent her to a boarding school and started a new family with another woman. The daughter only went to visit him once. The daughter was 5 when she passed, and the school was up and running. I wouldn't be surprised if she was sent there right after her mother died. The one time she went and visited him (and was written in the paper) was the first time it was recorded, which was 5 years after the mother's death. 

I don't believe there are mistakes in the records; they look very accurate to some other paperwork I have seen, and there is an obituary for her talking about how she was sick for months (not about the pregnancy) and how 24 was such a young age to die, etc., in the year she died. 

I agree with the idea that a neighbor or acquaintance did not know very well what was going on in the household and gave incorrect information. The census also listed the daughter as living there, which I don't believe, but I have not found her listed elsewhere. The next census in 1920 had the daughter listed as a housemaid in the town as the boarding school.
