Your website was forwarded to me from a cousin who found some discrepancies in some of your files relating to the Campbell family.
The information your have is about my Campbells and there are several mistakes, which lead me to believe somewhere you have your families mixed up - easy to do when so many had the same names.
I could correct everything for you, but unless you descend from the correct child of Benjamin PILLANS Campbell and Elizabeth Board (all children born in Paddington/Waverley) and Lorne Macdougall did not marry Marcia Yates, nor were his children the same as on your tree. Elizabeth Campbell married a King, Edith Campbell married a Leverrier and Ada campbell married a Lupton.
I descend from John Archibald Campbell, Benjamins' brother and I have his small family Bible listing all the children included the William you mention, who died at birth.
If this is your family and you let me know and I will send you corrections. I am also in charge of the Clan Campbell Society Library in Oz and have all their genealogical records, so could check our files if you give me details of what you are searching for. blgurney@iinet.net.au
