Hello Sue
I have received the mariage certificate for Thomas Lennox Seaton in Cairns, Queensland, Australia in 1899. He gave his place of birth as Douglas, Isle of Man, his father's name is the same Duncan Albert Seaton but his Mother is shown as Mary Catherine Duglass (perhaps this might be Douglas). He gives his age as 35. The family think he was older than he said he was. They have medals from his service in the Royal Navy and one is dated 1873-1874 in a battle at Gold Coast, Africa. If Thomas L. was born in 1864 as indicated, then he would have been 9-10 in 1873-1874, Perhaps his birth was never registered. I have't been able to find his parents marriage either. He is a mystery.
