Sources & References
A fair question about a site like this one: if the facts come from public sources, what does this page add? The answer is the checking. Most pages about Constantine Yankoglu repeat each other without ever going back to an original source, which is how invented details spread. This site went back. Every claim published here traces to one of the references below, each listed with what it supports — so you can verify anything on this site yourself, which is the point.
IMDb — the listing for Charles Yankoglu. Supports: his credit name, his birth date and birthplace, and his uncredited background role in Eight Men Out (1988), his only film appearance.
Motherhood and Hollywood: How to Get a Job Like Mine by Patricia Heaton (2002). Supports: the only first-person account of the 1984–1987 marriage, including her description of it as a rushed and incompatible match.
Patricia Heaton’s on-record interviews discussing her June 2017 Catholic annulment. Supports: the annulment date, the role of an Opus Dei priest in the process, and its significance for her return to Catholic practice.
Wikipedia and studio records for Eight Men Out (1988). Supports: the film’s production facts — director, release, filming at Bush Stadium in Indianapolis — used on our cast page.
What is deliberately absent from this list matters as much as what is on it. No source exists for his current residence, occupation, net worth, appearance, or education — which is why this site does not publish those details, and why pages that do cannot tell you where they came from.
