I am not sure if this is the right path.  My Great Great Grandmother was Ann Selina Rickard born 1849 in Tywardreath, Cornwall, England to John Rickard and Catherine Peters.  I have her marriage certificate when she married Alfred Johns in Yackandandah (just out of Albury, N.S.W.) Australia in 1871.  It clearly lists both her parents.  I had down in my tree her siblings being Temperance Ann, John, Jane, Catherine, Mary and William John but am not 100% sure this is correct.  Please make contact  and I can send you what I have.  Regards.
