My name is James Johnson from Bargara, Queensland, Australia. I am researching my Johnson Family Tree and have became 'Brick-walled' with finding my grandfather birth register records.

Details on hand are:

Name: William Frederick JOHNSON.
Birth: Ashford, Kent, England, 1891 (Marriage cert.) and 1889 (Death Cert.).
Marriage: Brisbane, Queensland, Australia, Apr 16 1921 to Florence SCOTT(B 1900 Ireland & D 1932 Brisbane, Aust.).
Death: Orange, New South Wales, Australia, Jul 9 1943.
Father: George JOHNSON (Inspector of Railways).
Mother: Emma STILES.

I have been researching (mostly on-line) using My Heritage for 5 years and a number of other ancestry sites periodically over that time. I have used BDM Register Offices for hard copy certificates where possible.
I have several theories about Williams birth but cannot cross reference any data to locate birth register details.

I am currently writing my Family Tree Book but am lacking on information re my grandfather and his ancestors.

Cheers
