There are a truckload of Richardson's in Orange county at various times. What does your date "9/4/92" mean? Is this day/month/year or month/day/year. And what year, 1792 or 1892? Better to write dates unambiguously as, for example, 4 September 1892, etc. I see 7 Richardson families in the town of Orange records for the earlier part of the 19th century, but none of these includes a Benjamin. Let me know if you have more data. There are also some very good LDS microfilm records, and published histories on microfilm.
