Do you have the names of their parents or other siblings?  There is no family group under the name of Philp that matches those brother's names, but if they had a 2nd name, they might have been enumerated by that.  The closest I have found is the following.  If they look plausible, I'll transcribe the family for you.--Genealiza
1880 Philp, John, 50, b. Scot
                  Ellen, 49, b. Scot
