It's difficult for anyone to help you based on just an individual name, as your ancestor could have lived in the UK in 1480 or South Africa in 1940!
You should include any of the following that you may know.
Location: Country > Province/Region/State/County > city, town of b, m, d.
Dates or approximate dates of birth, marriage, death.
Names of any siblings, spouses, children that might help identify the correct Richard Searcy.
