My wife is Susana de Pando. Her father was Luis M. de Pando y Ramsden. His mother was Emma Ramsden y de la Torre and Emma's father was Frederick Wollaston Ramsden, who married Susana de la Torre. They are my wife's great-grandparents. FW and de la Torre's daughter, Emma, married Fransisco de Pando. We know that FW's daughters, Emma and Dora, remained and married in Cuba. Their brother's (FW sons) seem to have been scattered around the globe. Does this help flesh out your tree?
