I've been searching for info on Pat Starling for years ... and finally hit pay dirt in 2016 with three information tidbits:

1. Newspapers.com had an article from the August 10, 1941 issue of the Courier-Journal newspaper from Louisville, Kentucky. The article was about entertainment at the Devou Park in Covington, Kentucky: "One young lady from Covington (Kentucky) who started as an entertainer on the Devou Park program is now in Hollywood making a picture with Douglas Fairbanks, Jr. She Is Pat Starling (Patsy McCartney to home folk) ... "
There's history on the Devou Park entertainment pavillion at: http://www.dreespavilion.com/history.asp

2. Ancestry.com had the Social Security Applications and Claims Index for Social Security updates and name changes for Patsy McCartney:
November, 1938: name listed as PATSY LAVERGNE MCCARTNEY
October, 1943: name listed as PATSY STARLING
July, 1961: name listed as PATSY LAV SCHWEIGER
November, 1982: name listed as PATRECIA L MAXWELL
Parents were Cornelius H. McCartney and Bertha C. Schuchter, and she was born November 27, 1927 in Kentucky.

3. During the 1940s, Starling became close friends with actress Yvonne de Carlo. That friendship carried over to the 1950s and 1960s when Starling was Pat Schweiger / Mrs. George F. Schweiger, Jr. of Sherman Oaks, California.

As noted above, Laverne Patsy McCartney was born November 27, 1927 in Kentucky. Her parents were Cornelius H. McCartney (nicknamed "Neal") and Bertha C. Schucter McCartney. The family was living in Covington, Kenton County, Kentucky in the 1930s but had relocated to Los Angeles at the time of the 1940 census. Father Neal was a parts and service manager for automobile dealers.

Adopting the screen name of "Pat Starling", Patsy McCartney appeared in about fifteen films during the 1940s.

There are tradezine and newspaper articles on Starling's brief Hollywood career. Of note is her age - born in 1927, she was about fifteen years old circa 1942:

• July, 1942 - 18-year-old Pat Starling, won the title of "Miss Victory of 1942" in a beauty contest at the Victory House in Pershing Square, Los Angeles. Prizes included a role in a movie.
• October, 1943 - filmmaker Charles R. Rogers signed Starling to a contract and a role in SONG OF THE OPEN ROAD (United Artists, 1944) which starred Jane Powell.
• November-December, 1943 newspapers carried reports that 18 year old Pat Starling had a movie deal. Because she was underage, she had to obtain court approval for that contract. From the December 1, 1943 issue of Variety: "Pat Starling's minor contract with Charles R. Rogers approved by court."
• late 1943 - Starling poses for Henry Clive's new series for The American Weekly magazine.
• her early work consisted of bit/minor roles including four uncredited appearances in 1943-1944 features at Republic Pictures (two with Roy Rogers, HEART OF THE GOLDEN WEST (Republic, 1942) and SAN FERNANDO VALLEY (Republic, 1944)).
• early 1940s - appears that Pat modeled for some erotic photos by Joseph Jasgur (1919-2009). He photographed many Hollywood celebrities and is most famous for his 1940s photos of Marilyn Monroe.
• In the late 1940s, she was the heroine in five westerns: with Jimmy Wakely in RAINBOW OVER THE ROCKIES (Monogram, 1947) and Sunset Carson in SUNSET CARSON RIDES AGAIN (Yucca/Astor, 1948), FIGHTING MUSTANG (Yucca/Astor, 1948), DEADLINE (Yucca/Astor, 1948), and BATTLING MARSHAL (Yucca/Astor, 1950). All five westerns were helmed by prolific producer, writer and director Oliver Drake.
• Starling became a close friend of actress Yvonne de Carlo. The October, 1951 issue of Modern Screen highlighted their women's Fashion Board and board members included "Yvonne de Carlo and her friend, starlet Pat Starling."

Starling then disappears from films and the movie business. Patrecia L. McCartney marries George F. Schweiger, Jr. in 1951 ... and begins a new life in San Fernando Valley, California society. They reside in Sherman Oaks, California and have a Malibu beach house. And Pat Schweiger volunteers for all kinds of charitable events and activities including the support of the Los Angeles Philharmonic Orchestra and the San Francisco Opera. The Newspaper Archive website had dozens of articles - many with photos - of Pat Schweigher / Mrs. George F. Schweiger, and most were from the Van Nuys (California) The News newspaper. Additional info was found in movie fan magazines, Ancestry.com and the Social Security Death Index (SSDI). And Pat was still buddies with actress Yvonne de Carlo. Summaries follow:

• 1955 - actress Yvonne de Carlo marries stuntman Robert Morgan in Reno, Nevada. Mrs. George Schweiger was matron of honor. The March, 1956 issue of Modern Screen magazine had a photo from the wedding and the caption read: "Yvonne De Carlo and Bob Morgan eloped to Reno and surprised everyone - except Lita Baron Calhoun and Pat Schweiger who were bridesmaids." (Lita Baron was an actress and wife of Rory Calhoun.)
• 1956 -1967 - Pat Schweiger / Mrs. George F. Schweiger has various roles as member, president and/or hospitality chair of the Valley Committee for the Los Angeles Philharmonic Orchestra. The group is also involved in the San Francisco Opera.
• November 13, 1964 issue of the Van Nuys (California) The News reported on the celebration of Pat's November 27 birthday: "Birthday ... of Mrs. George F. Schweiger Jr. ... will be celebrated when members of the Valley Committee for Philharmonic Orchestra meet for dinner and take bus to opera Nov. 27."
• she and her husband hosted a December, 1965 Christmas dinner at their Sherman Oaks, California home. Guests included Yvonne de Carlo and husband Robert Morgan and Nick Firfires and wife Maxine Beery (daughter of Buck Jones and recently divorced from Noah Beery, Jr.).
• George F. Schweiger Jr. (born 1917) married Patrecia L. McCartney (born 1927) in 1951 and the Preliminary Dissolution of their marriage was March, 1968.
