Colleen,
In your original note you mention Dennis Toynbee who married Mary Martin. You should know that his name was actually John Dennis Toynbee. He was my great-great-grandfather. They were originally from Burry in England but moved to Scotland when my grandfather (also John Dennis Toynbee) was around 2. John Dennis Toynbee married Jessie Forester Gillon in Scotland. They had three children - Margaret Monteith Gillon Russell (nee Toynbee), John Dennis Toynbee and Rosemary Crookston (nee Toynbee).
The William Toynbee, in Edinburgh, that you mention is my mothers Uncle Willie and was married to Rebecca.
