Ellen Murphy and brother Patrick

Hi I'm looking for information, obituary, descendants etc of Ellen Murphy born in Co Kerry Ireland in 1885, I recently came across information that her brother Patrick arrived in Ellis Island in June 1909 and the destination address he gave was hers:Ellen Murphy, Box 197,
Thompson, CT
Patrick was born in 1881, now we may not even be related but there are too many similarities for it to be a coincidence.
Any help would be greatly appreciated
Sarah
