I've read the information provided in the magoo.com: McGoughs McGoughs and McGues in the 1900 Census of the ... , Cambria County, Carroll Township. The census record is accurate but there seems to be some confusion about Sarah and Magdelen.
Sarah McGough (Dumm) b. December 25-1879 d. January 13-1936 was the wife of Joseph McGough b. March 7-1879 d. May 27-1961. (Joseph's birth year on his tombstone is wrong)
The confusion with Sarah is that she used her nickname "Sadie" on many of the records found for her including her Marriage Application to Joseph and Birth Certificates for some children.
However on her funeral arrangment records her name is stated as Sarah, A Grand-Daughter named after her was Sarah, and when she and Joseph stood for the christening of a grandchild her name was Sara (Mispelled). The information provided has been verified.
Simon McGough was the father of Joseph McGough and Pius McGough b. 1881 possibly March d. March 29-1956. Simon's wife was Margret Hershel who after the death of Simon and before her second marrige to John A Trinkley appears to change her name to Magdelen. She is buried under the name of Magdelen Trinkley in the St Mary/St George/Queen of Peace Cemetery , Clearfield Township, Cambria County, PA beside her second husband John A Trinkley.
Though she used the name Magdelen while married to John A Trinkley, her name stated on her Death Certificate is again Margret and her birth is stated as Unknown.
The above book states that she was born in 1848 howver she died on November 14-1913 at age 53. making her birth year at 1860.
Pius is also buried in this cemetery in an unmarked grave and possibly in the Trinkley Family Plot. However the cemetery records of 1956 were poorly kept and no record of which plot Pius is in is available.
Nothing to verify the death of Simon has yet been found.
