Looking for info on Mary Casey and Edward Sullivan

I'm looking for any info on Mary E. Casey who married a Edward B. Sullivan. They lived in Chicago from the late 1800's to the mid 1940's. Mary and Edward had 2 nieces that came to live with them they were Daisy and Betty Casey they were sisters. They were from Ireland.

I don't have any info on Mary when she married Edward. I don't need help with the census. I'm just wondering if anyone had any information on Mary and or Edward. I know they owned a furniture store downtown Chicago.

I'm trying to connect Mary to my family.

Can email at [email protected]

Thanks for the help,
Milissa Casey
