Thank you for this tip. I agree that "BROCKMAN" could easily be an interpretation of "BROCKWAY". Family Search consists of records transcribed by volunteers, and if the transcriber was not familiar with the name BROCKWAY then the name could have been misread.
I shall have to make some new searches on Family Search. There is a lot of new data appearing there now, as the LDS makes a large effort to increase volunteer transcription hours.
