Alexandria's historic Christ Church was the setting on April 11 for the marriage of Lydia Anne Weir Sandlund, daughter of Mr. and Mrs. Peter Gustaf Hugo Sandlund of Alexandria, Va., to John Hayden Aldredge, son of Dr. and Mrs. George N. Aldredge, Jr. of Dallas, Tex. The Rev. Mark Anschutz officiated, and the bride's brothers, Eric, Christopher, and David Sandlund, read the lessons of the Episcopal service.

Given in marriage by her father, the bride was lovely in white linen and alencon lace and wore an heirloom gold and pearl brooch originally worn in Sweden by her great-great grandmother. Mrs. Robert Dean Fazakerly was matron of honor. Anne Aldredge, the groom's sister, and Catherine Varino and Nicole Jullienne, the bride's cousins, were bridesmaids. Christopher Aldredge, brother of the groom, was best man, assisted by their younger brother, Matthew Aldredge, Sten Sandlund, brother of the bride, and Paul Bernardo.

For the reception which followed, chamber music and spring flowers filled the Boyhood Home of Robert E. Lee in Alexandria. The wedding cake was adorned with a scale model of Christ Church, constructed by the bridal couple, both architects.

Mrs. Aldredge attended H. Sophie Newcomb College in New Orleans and graduated magna cum laude in history and fine arts from the College of William and Mary. The bride holds a master's degree in architecture from the University of Oregon, as does Mr. Aldredge, who also received a bachelor's degree in architecture from the University of Virginia, where he was a member of Sigma Alpha Mu Fraternity.

Following a wedding trip to Victoria, Bristish Columbia, the couple is making their home in Seattle, Wash., where they are pursuing careers in architecture.
