No , the two are distinct persons . Dennis the Menace was played by Jay North and Alice Cooper whose real name is Vincent Damon Furnier .
Dennis the Menace (1959 TV series) aired from October 4, 1959 - July 7, 1963 and the comic strip by Hank Ketcham debuted on March 12, 1951 and is still an ongoing comic strip .
Jeannie Russell played as Margaret Wade who was Dennis' nemesis in the TV series .
Miss Gina Gillotti. her mother was an obvious take-off on a more famous Gina. The episode ( in cartoons) the Chow Hound shows how Dennis misunderstood Italian word Ciao ( meaning Goodbye) for American Slang Chow meaning Food! -to get himself a free meal at the Gilotti"s Mama Gina looked like her Hollywood namesake, wore Old-country dresses. Nice in days of NATO to have an Italilan family as neighbors in Dennis.
Dennis Mitchell lived at 627 Elm Street .
No , Jay North (born August 3, 1951) is still alive .
Hank Ketcham was the cartoonist involved. He worked an Italian family in as supporting characters. Gina Gilotti was a neighboring girl about Dennis" age. Misunderstandings of the Italian language led to some ( sano) ethnic comedy. Gina"s mother looked like her Hollywood namesake! In a sense Dennis got me interested in the real Gina Lollobrigida.
Tommy Anderson was played by the late Billy Booth (November 7, 1949 - December 31, 2006) who passed away from health problems with his liver .
The TV series was located at Columbia Ranch in Burbank, California (now the Warner Ranch) was the backdrop for the series .
Dennis usually wears bib front overalls in the TV series .
I believe he resides in Florida.
As a comic strip and originally block cartoon ( one block per day) it was irrelevant for marketing reasons- Dennis was syndicated all over the United States. It might be noted some juvenile comedy shows did have tied-down stakes, so to speak. I seem to recall that Leave it to Beaver was set in the Chicago area, based on somewhat heavier togs worn by characters, I vaguely recall some dialogue suggesting this. My Three Sons was in suburban California. Dennis, it was not relevant to the plot.
Hank Ketcham's cartoon strip "Dennis the Menace" debuted in 1951 .The Beano's Dennis the Menace, a totally different character, also debuted in 1951, 3 days after Ketcham's.
The US TV cartoon Dennis the Menace main character's last name was Mitchell.
George Everett Wilson from next door since he is less enamored with Dennis as is the others in the neighborhood .
