Fletcher Portwine

William Mack Fletcher married Gertrude Eveline Portwine in Victoria in 1940. He served in WWII in 1942

Can anyone assist me with William Mack Fletcher's family? I know William Mack was born in India where his father, also a William was a missionary?

I think William Mack had a sister Gladys.

Thanks in advance for any help.
