Okay, I think you’re saying that if kiwitrees was English only, strict date entry used, it’s possible.
Actually not even that – you would probably want “mm/dd/yyyy” but I and all my English-speaking friends would prefer “dd/mm/yyyy” 🙂
Was hoping to reduce overage searches. When I want births before 1916 (cutoff for Ontario), +/- 10 gives me up to 1926.
Try entering 1906 +/- 10. (or 1911 +/- 5). That cuts your list down to 1916.
