In the process of my gamily genealogy work, I have discovered that I have a half sister. I do not know her name. I have been told that she is married to a Robert Toigo. They have at least two children. They met with my father (James Roppo) probably sometime in the 1970s on the far south side of Chicago at the home of my paternal Grandmother. Robert Toigo has a cousin named Dennis Toigo who grew up in the Roseland area of Chicago. Does anyone connect with this? Again, I am searching for the wife of a Robert Toigo. Thank you.
