Vlach ( /ˈvlɑːk/ or /ˈvlæk/) is a blanket term covering several modern Latin peoples descending from the Latinised population in Central, Eastern and Southeastern Europe. English variations on the name include: Wallachians, Walla, Wlachs, Wallachs, Vlahs, Olahs or Ulahs. Groups that have historically been called Vlachs include: modern-day Romanians or Daco-Romanians, Aromanians or Macedo-Romanians, Morlachs, Megleno-Romanians and Istro-Romanians. Since the creation of the Romanian state, the term in English has mostly been used for those living outside Romania.

The Vlachs, which would develop into the modern Romanian ethnicity, do not become tangible before the High Middle Ages in Kedrenos (11th century), and their prehistory during the Migration period is a matter of scholarly speculation but according to the linguists and to many scholars, the existence of the present Eastern Romance languages prove the survival of the Thraco-Romans in the low-Danube basin during the Migration period and the Vlachs are all being well considered descendants of Romanised peoples of the area (incl. Thracians, Dacians and Illyrians).

Skip Heitzig (born 1955) is the founder and senior pastor of Calvary of Albuquerque, a Calvary Chapel fellowship located in Albuquerque, New Mexico.

A native of Southern California, Heitzig has three siblings (his brother, Bob, died in a motorcycle accident in 1975).

He's been described as a former marijuana smoking surfer dude. Heitzig was witnessed to by a friend, Gino Geraci, senior pastor of Calvary South Denver. He had tried to talk about God with him before but he never seemed to get through to him. This time, Heitzig was moved. Heitzig was finally moved to become a Christian while watching a TV message by Billy Graham. Shortly after this experience, Heitzig began to study under Pastor Chuck Smith of Calvary Chapel of Costa Mesa.

His early training in radiology was through UCLA which included an internship program at San Bernardino County Medical Center in San Bernardino, California. In 1981, Heitzig married his wife, Lenya, and together, they moved to Albuquerque, New Mexico to continue his work in the medical field. Together, they have one son, Nathan.
