In 1830 it is interesting to note that both Archibald and John F. Darrah appear on the tax rolls from Buckingham. This was the sole entry for the both from this location. Searching Buckingham for the years 1828 and 1831 show no other Darrah listings. (There was no 1829 tax listing from Buckingham.).
Starting again in 1831 we find Archibald and John F. listed from the town of Solebury. We point out that Plumstead and Solebury border each other. Regardless of the significance of that factor, Archibald paid his taxes from Solebury from 1831 to 1837. The last year we find Archibald paying his taxes in Bucks County was 1837. Aside from the above mentioned locations within Bucks County the only listings for an Archibald Darrah was an 1800 listing from New Britain.
