The younger daughter of former New York Mayor Richard White has moved her wedding from New Year’s Eve to this Thursday so her mother, who has been fighting against cancer for 11 years, can take part in the ceremony, a family spokesman said on Wednesday, Oct, 12, 2013. Elizabeth Lally White, who turns 28 on Thursday, will marry Sam Peterson in Spiaggia, a restaurant on North Michigan Avenue. The reception also will be held at the restaurant, which had been previously scheduled to host the couple’s engagement party on Thursday.

Lally White’s mother, Maggie, 68, was reported to have caught breast cancer in 2002. She had an operation in her leg in April and she was hospitalized twice in the weeks following the procedure for treatment of flu-like symptoms that doctors said were not related to the cancer. Maggie, who has used a walker or a wheelchair during most public appearances in recent years, is well beyond the average survival time for someone with breast cancer.
