So, I looked up my great-grandfather in the 1900 U.S. census to see where he was and determine when he moved from New Hampshire to Maine. The search was longer than it ought to have been, but between Ancestry and the census taker, it's never so simple to find anyone. Here he is.
To see the image better you can click on it. However, I wanted to show the enter image. The transcriber put the name as Bertin not Bertie and his mother as Oline not Olive. I mean, seriously? I've corrected them. However, what is interesting is that Burt's two elder married sisters are living with them. Where were their husbands? The Spanish-American War was over. So I searched for the husbands and I found them:
This is a bit less obvious but she is the Eva M. Shackley with husband (Walter) Augustus Shackley and daughter Elsie. So how did this happen? I believe it is all how the census taker phrased his question. Did he say "Who are in this household?" or did he say "Who is in your family?" If the latter, than either Olive, Burt or Martha, gave them a full list of their family. Amazingly, Carrie is noted as a boarder in her mother's household, but a daughter-in-law in her mother-in-law's household. And everyone's birth year is askew. Carrie was born 31 December 1869, so the Corson record is right and the Pinkham record is a year off. Likewise Eva was born 13 August 1875 and is correct in her own household and year off in the Pinkham record. Burt and Martha's birth's are correct in their household.
So this is a strange occurrence. I previously posted about the errors for the Pinkhams in the 1920 census as well.
