Hi! According to the 1880 census of Chicago, Cook County, Illinois, there is a Tim Sullivan listed there and in his household there is a Maria Cassiday.
I am researching the Sullivan line and would like to find anyone who would be related to this Sullivan/Cassiday line.
Feel free to email me direct at Allaire2004@aol.com
In the census is mentioned - Tim(husband), Anna(wife) and their children - Anna, Maria, Nelly, Magie and Meike. As well as Maria Cassiday listed as other. I am thinking Maria could be Anna's (wife) mother.
