I see my original query was rather brief!

I am looking for a Nellie Davey nee Gilhooley/Gilhooly. She was born September 1872 in Massachussettes. Her parents were Thomas and Anne/Anna/Hannah. They were both born in 1850 and 1851 (respectively) in Ireland and were married in 1872. They came to America 1867 - 1869. Their first four children were born in Massachussettes including Nellie/Nelly (who looks to be a twin to)Joseph, Charles and Mollie. Two younger children, William and Edward were born once the family had moved to Chicago in 1879 and 1885 respectively.

I have found this family in the 1900 and 1910 Census in Chicago.

Nellie married Michael Davey in Chicago in 1895. They had four children: Mona, Bernice, Leona and Bernard.
