I wasn't thinking I'd get much from this record, since I don't put much faith in user-submitted records, but that source mentioning the 1901 census entry got my attention. I hadn't been able to find Henry and Sarah Jane in the 1901 census (or any census after 1881). So I looked again, and I found Henry! I don't know why I didn't find this before! I know it's him because he's living with two of his children, and their names and birth dates match children from an earlier census! This is definitely a step. Thanks so much, Fred!! :D
