Question: When was actor who portrayed the owner of the Southfork Ranch in the soap opera, "Dallas," born?
Context: Patrick Duffy (born March 17, 1949) is an American actor, best known for his role on the CBS primetime soap opera "Dallas", where he played Bobby Ewing, the youngest son of Miss Ellie and the nicest brother of J.R. Ewing (played by Barbara Bel Geddes and Larry Hagman) from 1978 to 1985 and from 1986 to 1991.  Duffy returned to reprise his role as Bobby in a continuation of "Dallas", which aired on TNT from 2012 to 2014.  He is also well known for his role on the ABC sitcom "Step by Step" as Frank Lambert, from 1991 to 1998, and for his role as Stephen Logan on the CBS daytime soap opera "The Bold and the Beautiful" (2006-2011).  Duffy played the lead character's father in the 2014 NBC sitcom "Welcome to Sweden". The Cloyce Box Ranch was the site of the original Southfork ranch location, where the initial five episodes of "Dallas" were filmed.  The series left that location at the end of the first season in 1978 due to a request by the property owner Cloyce K. Box.  The show moved to the ranch "Duncan Acres", near Plano, Texas, where the series was filmed for the rest of its run. Veronica Martinez known by her alias Marta Del Sol is a fictional character from the American soap opera "Dallas", played by Leonor Varela.  The characters of J. R. Ewing (Larry Hagman) and John Ross Ewing (Josh Henderson) feature heavily in Marta's storyline.  Marta partners with the duo and they attempt to steal the Southfork Ranch from Bobby Ewing (Patrick Duffy).  Marta falls in love with John Ross and Varela said that it is one of Marta's more genuine moments.  But she believed that John Ross would never be able to maintain the same respect for her.  With similar personalities they are well matched; but John Ross' relationship with Elena Ramos (Jordana Brewster) causes Marta to become jealous and obsessive.  Varela's departure was announced in July 2012.  Marta was murdered and John Ross wrongly accused of the crime.

Dallas is an American prime time television soap opera that aired on CBS from April 2, 1978, to May 3, 1991.  The series revolves around a wealthy and feuding Texas family, the Ewings, who own the independent oil company Ewing Oil and the cattle-ranching land of Southfork.  The series originally focused on the marriage of Bobby Ewing and Pamela Barnes, whose families were sworn enemies with each other.  As the series progressed, oil tycoon J. R. Ewing became the show's breakout character, whose schemes and dirty business became the show's trademark.  When the show ended in May 1991, J.R. was the only character to have appeared in every episode.
