Relda lived in Berlin, Germany, until she met Basil Grimm. They were married shortly after they met, going on a two year honeymoon, "Packing a lifetime of vacations" into that period of time, seeing wonders of the world. On the honeymoon she learned several strange recipies. (see Relda's Cooking)

Relda had two children; "Hank" Henry Grimm and "Jake" Jacob Grimm. As far as we know, Jacob remains single. However, Henry marries Veronica Grimm and they eventually have three children; Sabrina, Daphne, and "Little" Basil.
Relda eventually finds her oldest grandchildren (not yet knowing that Basil exists) in the foster care system, and gains cudstody of the girls. Although Puck is not techically one of her own, Relda took it upon herself to care for him.
"Granny" Relda is known to cook strange things such as Camel's Hump Soup, Blue Meatballs, and Pink Syrup.

Relda often wears colored dresses with a matching hat, a sunflower appliqued into the center. She has gray (but still slightly streaked with its former flaming red) hair, usually in a bun with a few strands loose. She is "A little pudgy" and seems "Too young for her wrinkled face...because of her rosy cheecks and sparkling green eyes.
