Theophanis K. Nikopoulos (also known as Frank Nixon) was born in Viniani, Evrytanias on April 23rd, 1890 to Konstantinos Nikopoulos and Peristera Triantogianis. In 1905 (at the age of 15), he immigrated to America and settled in Clarksburg, West Virginia where he found employment in restaurants. In 1914, he returned to Viniani and remained there until returning to America in 1921. In 1915, Frank contributed to the community water system in the center of Viniani for all of his fellow villagers to have access to clean water. That same year he funded the construction of the Nikopoulos family home which is still standing today. In 1917, he married Virginia Kleitches (January 4th,1898-December 31st, 1986) who was the daughter of Demitrios Kleitches and Amalia Markos.

Frank made numerous trips back and forth to Greece resulting in all four of his sons (Xenophon, Stavros, Kostas, and Dimitri) being born in Viniani. In 1937 he brought his oldest son Xenophon to America to join him in Clarksburg, where he owned a restaurant and hotel. In 1946, he brought his wife Virginia as well as his other three sons to America. That same year the entire family moved to Charlotte, North Carolina to be near to fellow Evrytanians. Frank Nixon helped his three oldest sons get established in business by purchasing the Elite Coffee Pot grill in downtown Charlotte. In 1948, they bought the Superior Lunch Grill which enabled his sons to secure a future in the restaurant business. After his death in 1951, Frank's widow Virginia continued his legacy by funding the construction of Agia Triada chapel and the renovation of the prayer station of Agios Spiridon, both of which were completed in 1954.
