I am a yebury, in heart, my mother's maiden name is yerbury and it is the only family I have ever known, there are yerbury's in Utah, I don't know if you are aware of them. I live in Corvallis OR. I can only seem to trace back to an ansestor named Thomas in 1630, The LDS history library has him buy the name Thomas Yerburg instead of the recent Yerbury name. If someone has knowlegede of his predecessor please pass it on.
Sincerely Jessica Yerbury Engler
