I have, since posting, found that Ellen (Elena, Eleanir) DORMAN, probably of Cork, b.1817, married Lawrence HAYDE, b.1812 in Tipperary or Limerick. Their children, born 1835-1850 in Glamorgan, were -Mary, John, Michael, Thomas, Annie, James, Richard, and Ellen.
Annie came to Queensland from Liverpool on the "Rajasthan" in 1862;there are other connections in New Zealand.
Thanks for your interest; I look forward to hearing more from you if any info. comes your way.
