Hi Phil,
Patrick was my great-great-great grandfather and I was named after him. I have a picture of his tombstone (located in Salida, Colorado) and it states he was born in Roscommon, Ireland on May 4, 1832 and died on September 17, 1885. Many members of the Rush family are buried in Salida including Patrick's son, Charles (my great-great grandfather) and his grandson William (my great grandfather). I am unfamiliar with much history prior to Patrick, but I know a little about the time afterwards.
