Hello All
Try this
William Paxton Unthank (Grandfather B1854 - D1916) had numerous children
One son, William Unthank (B1888 - D1970) married Anne Davidson in 1910, they had a son named William Paxton Unthank in 1911, but he died shortly after birth.
Another son James Unthank (B1892 - D?) married Mary Hastie in 1910, had 3 sons and a daughter. Eldest son named William Paxton Unthank (again) B1911 - D2002
Hence I believe the newspaper article has the sons attributed to the wrong brother.
