McLennan Marries Twice?????????

NSW State Records in Australia show that John T Finlay married Annie G McLennan in early 1920's in New South Wales, Australia.

If this is the same Annie G, then she must have married John T before she married Charles Elmer Vance from USA in Sydney, NSW, Australia in 1926.

That makes one think as no one seems to know anything about the first marriage.

Can anybody through any light on the subject, please??
