Frank Cartledge BALL and his wife Alice Graham Agnes nee CHRISTIE

I received the card below amongst articles that belonged to my great grand uncle, Alexander MORGAN of Johnsonville, Wellington, New Zealand.

Grand Canal Venice April 1927.  
"Dear Mr & Mrs Morgan, with Christmas greetings from Alice and Frank Ball.  Christmas 1928."

Frank Cartledge BALL (1868-1934) was a journalist and he and his wife Alice Graham Agnes nee CHRISTIE lived at 98 Riversdale Road, Camberwell, Victoria.

Any connections out there?
