I amy be beating a dead horse here, but I found some old notes indicating that J.B. Kemp was the foreman for an H.F. Williams & Company in the 1869/1870 City Directory for San Francisco. H.F. Williams was the City Paving Comapny located at 619 Montgomery in San Francisco. I believe this company would have laid the pavement for early San Francisco streets. The furniture company of J. Kemp was probably a completely different outfit. A paving company would have been more likely to have hired Irish immigrants to do the manual labor than a furniture company which, presumably would have required skilled craftsmen & fewer laborers.
