Suzanne on Family Tree Circles

Am looking for information on Curran Family who lived in New Britain
CT. John Edwin Curran Married a Margaret Tierney.
They had, I believe 7 children.
Looking for information on Richard Curran born about 1861 and whether he married or not.
Eunice Curran was a twin of Edwin Curran born 1897 and believe he moved to Arizona. Do not know if he is alive or dead and if he ever married.
Sidney Curran born 1895 and died 1977 in CT. He was a druggest but do not know if he married.
Any info would be greatly appreciated.
There are no family relatives for me to ask, they are all deceased.
Sure wish I decided to do this ancestry hunting while they were alive.
Thanks.
