Found a few things that might be interesting, but I'm starting to lose track of what has been found already.
Apologies for any repeats.
An obituary of Mrs. Mary J. Bryan in the Gettysburg Times from 23 Apr 1928. She was a daughter of the late Mr. & Mrs. Charles Costa, was born in Philadelphia, and spent most of her life "here" (Gettysburg, I presume). C.A. Crosta of Denver was a brother. Other siblings include: Mrs. Charles Codori, Los Angeles; Edward C. Crosta, Oakland, California; John Crosta, Los Angeles; Mrs. Emma Noel, Baltimore street; Mrs. Charles Schleieh, Philadelphia.
In a story from Florence, Colorado (UP) in the Chillicothe Constitution-Tribune, 23 Jan 1935:
"Because he will neither swear nor affirm, wedding bells shall not ring for R.C. Crosta, 31. Crosta recently went to the county clerk's office in Pueblo to apply for a license to marry Miss Virginia Williamson, 19. When he would not swear to the truth of the statement he had made in the application, the clerk reminded him that a simple affirmation in cases of religious scruples against taking oaths. Crosta refused to affirm and the clerk refused the license."
There's also an obit for Chas A. Codori in the New Oxford Item from New Oxford, Pennsylvania on 15 Jan 1897. It mentions that he was a native of Gettysburg and was married in 1887 to Kate A. Crosta, daughter of Charles Crosta, dec'd, who for many years resided near Irishtown, Oxford twp, who, with one child, survives him.
