Your grandmother Chrystalia's younger sister Iris, was my step-grandmother. Her name was Iris Yolanda Williams, born December 23, 1907, St. Croix, Danish West Indies. I think she was born in Christiansted. I believe she also had a sister, Celita Williams, and brother, Basil Williams. Both are deceased. Celita's son, Henry Williams lives in St.
Croix. Iris married Milton Gerard Todmann of Frederiksted. Iris died in 1997 and is buried in St. Croix in the Frederiksted cemetery. Richard is correct about the spelling of Todmann with two n's. I will email you when I get more info. Good hunting.
