She met her husband James McIver at the fruit market and they set up their own business hiring out horses and carts to local hawkers.
In 1926, Maggie McIver decided to cover the market mainly to protect clothing hawkers from having their stock ruined.
[3] It was common practice for McIver to host a Christmas party for the hawkers and their families in a local hall.
One year, when McIver was unable to hire the hall, she decided to build her own, the famous Barrowland Ballrooms which opened Christmas Eve 1934.
A plaque has been added to the Barrowlands Ballroom to commemorate Maggie McIver as part of twelve Scots being honoured by Historic Environment Scotland (HES).
