I believe SAG has microfilmed records from St. David's so I might pay a visit to them to see if I can find out more information. The marriage certificate for Myrtle said she was living at 415 Riley Street, Sydney at the time of her marriage.If you let me know where to send them I can forward copies of extracts I have which might be more helpful. As to the third child, I am not sure now. I think it was from family stories but I can't seem to find anything to verify this. It is just a suspicion.
