Your family would own many precious historical documents and items. You might have a collection of old photographs, papers from Grandpa's business, old love letters or letters sent back from the Front in the First World War, Grandma's wedding dress or even Aunty Joan's 1950s belle of the ball gown.

Proper storage of family treasures will help preserve them for future generations. Sadly, we no longer have Grandma's wedding dress, but this is the wedding photograph of my Grandparents, Joseph Rouse and Eva Weatherhead, who were married at the Methodist Church at Garfield on November 22nd, 1922.
