Singular Motto

Being at Cheltenham in the summer of 1811, I saw a chariot standing in an inn yard, on the panels of which, under a coat of arms, apparently belonging to some foreign family, was the following on a scroll, in the nature of a motto: —"oemn3—ononoe.7 ano—7 emn3." If any of your correspondents can inform me what is its meaning, and if it be a motto, to what family it belongs, he will oblige.
