Kerry, There certainly is another couple looking for the same family. We've been looking for years!! My husband, Keith Ferguson, is the grandson of William John's brother, James Boyce born 1875 at Wallaroo. Have been in contact with some of the descendants of your William John, Margaret Jane 1857 and Andrew 1864, so have a lot of info. if you are interested. Includes lots of B.D.M. certificates. We live in Lilyfield, Sydney so please let us know if you're close enough to ring. You are the only other person researching this family that we have come across. Can't wait to hear from you.
