Sometimes it's not the transcriptions of the information in a census, but the actual information. I wonder who talked to the census taker in 1920. I'm guessing it was one of the kids. In any case, Olive Pinkham was Burt's mother not his wife. She moved in to help with his three sons after his wife Kate died in 1918 in the influenza epidemic. He was born in Dec 1881 and was 38. She was born in June 1851 and was 68. The image is too scribbled to be clear on that score. So the ages are correct for January 1920. She was also born in New Hampshire not Maine. My grandfather is the Clarence listed as 7. He just died in 2007.
