So IF she married, and IF the children were born in NSW, then as she was born 1908, even her eldest child would not yet be 100 years of age, so you will not be able to find their NSW BDM births listed on the indexes.
So, IF she married in NSW, it is likely she was married before 1964 (born 1908). I have searched the online index for a marriage for a Jeanette TOOHEY from 1908 until 14/05/1965. I cannot find one.
Is it possible that she married in another state, or perhaps in New Zealand? .... or elsewhere ?
Is it possible that she did not marry ?
May I support Wivenhoe's question ..... Do you mean that you know that Jeanette married .... or are you looking to find if she married?
Cheers, JM
