Your question on this thread, was something I have been working on, so I thought I would create a blog about it.
I have spent most of the day cleaning up my Census Records. Starting with the Template feature, but now am re-doing how I do the Websearch on Ancestry for Census Records. Before, I did the search on anyone, but now have changed to just do the Web Search and Web Merge on the Head of Household. BUT, then I pick up everyone on that Census Record for that Household. Various Census years, at Ancestry merges the family differently.
