I am also looking for William Pender Scotland to Australia. I believe he may have married Flora McLachlan in Sydney in 1853. I also think he arived in Australia in 1839 on the ship British King, aged 14 and travelling with his parents John Pender and Mary nee Bowie, plus some siblings. I have not been able to find any definite record of William & Flora after their marriage, but I have found the burials of John and Mary in the Hiland Crescent cemetery. My connection is through Flora McLachlan who was the sister of my great grandfather.
