Hi Rosie,
Thanks for the quick replies and the information. Does it list a date or just the year for her birthdate?
I have very little information about her parents; all I know is that they both died when she was young, they probably lived in Greenock, and that their surname was probably Craig. She kept it as a middle name when she married and dropped Masson in favour of her husband's surname. Her husband's name is Alfred Jennings Clarke, dob. 13.6.1881, Kew, Victoria, Australia, died 27.7.73 in Melbourne, Australia. He served in the AIF in WWI (infantry) - I presume they met in the UK while he was training there. He served in northern France in 1917-1918, returned to London in late 1918, married Mary in Kirkintilloch in April 1919, then returned to Australia in June 1919. There's no record that I can find of her transport to Australia, but her son was born there in 1921.
Thanks again,
A
