Hello Joan,

I didn't answer you before because I'm in a different time zone - so by the time I received your reply Sylvia had already found the information for you from the details you gave.
However I'd like to make sure that you saw my message on the list, just above your first one, which gives the step by step method of searching the 1911 index, so that you will be able to find anyone else you need at that time. (You asked "does anyone know if or how i can find out").
