So I was sitting and thinking about my new granddaughter just now. Her mum and dad call her Jedda which is a name that I’ve never heard before. Apparently Allan met a woman with the name and really liked it and it went from there.
So Wikipedia said:about Jeddah also known as Jedda
There are at least two explanations for the etymology of the name Jeddah,according to Jeddah Ibn Helwaan Al-Qudaa’iy,the chief of the Quda’a clan. The more common account has it that the name is derived from جده Jaddah,the Arabic word for “grandmother”. According to eastern folk belief,the tomb of Eve (21°29′31″N 39°11′24″E / 21.49194°N 39.19°E / 21.49194;39.19),considered the grandmother of humanity,is located in Jeddah.[4] The Tomb was sealed with concrete by the religious authorities in 1975 as a result of some Muslims praying at the site.
Ibn Battuta,the Berber traveller,visited Jeddah during his world trip. He wrote the name of the city into his diary as “Juddah”.[5]
The British Foreign Office and other branches of the British government used to use the older spelling of “Jedda”,contrary to other English-speaking usage,but in 2007 changed to the spelling “Jeddah”.[6]
T. E. Lawrence felt that any transcription of Arabic names into English was arbitrary. In his book Revolt in the Desert,Jeddah is spelled three different ways on the first page alone.[7]
On official Saudi maps and documents,the city name is transcribed “Jeddah”,which is now the prevailing usage.
From Saudi.net I found the following:
The name Jeddah meaning the “Ancestor of Women” is attributable to the tomb in the city which is believed to belong to Eve. Today,it is not however possible to see that interesting place since the Saudi Arabian government had the tomb destroyed for the reason that it would instigate perversions in the religion. Jeddah which gained importance during the Ottoman rule,was incorporated into the Kingdom of Hejaz and later came under the British control. It joined the Kingdom of Saudi Arabia in 1927.
I also found a movie named Jedda which takes place in Australia where the title character is Australian.
Some baby name sites say it is an Australian name and others say it is an English name. Several of the baby name sites had no meaning listed though a couple said it meant “Jet Black Stone”.
