I looked up the Connection for "12 Apostles" to see if it had the Tomb of ST John (Basilica of St john at Ephesus - https://en.wikipedia.org/wiki/Basilica_of_St._John
). It doesn't.
But I then noticed another Connection for "Tombs of Biblical Figures". It has entries for
Ephesus - Tomb of St John (The Apostle)
Aleppo - Tomb of Zechariah (Father of John the Baptist)
Jerusalem - Tomb of Jesus
Samarkand - Tomb of Daniel
Vatican - Tomb of St Peter (The Apostle)
i.e Tombs for 2 of the Apostles.
The "12 Apostles" Connection has entries for
Armenian Monasteries - tomb of Apostle Thaddeus
Derbent - where St Thaddeus was traditionally "flayed alive"
Patmos - Tomb of St john (who may have been the Apostle or another "John" altogether)
Jerusalem - as the location for Apostles living/meeting in general
Santiago de Compostela - Tomb of St James (son of Zebedee)
Vatican - where St Peter was traditionally crucified (no mention of his )tomb")
There is overlap and inconsistency across these 2 "Connections".
a. There are tombs of 2 Apostles in the Apostles Connection which are not in the "Tombs of Biblical Figures" Connection - Armenian Mons for Thaddeus and Santiago de Compostela for St James
b. The 12 Apostles definition doesn't really say what the requirement is
c. As I understand it St Batholomew (NOT Thaddeus) was flayed/crucified at what might now be Derbent
d. In fact the remains of several Apostles are believed to be at St Peters - St James ("the Less") and St Philip. St Thaddeus is also known as St Jude" and his remains are also claimed to be in St Peters ("Sometime after his death, Saint Jude's body was brought from Beirut to Rome and placed in a crypt in St. Peter's Basilica which was visited by many devotees. Now his bones are in the left transept of St. Peter's Basilica under the main altar of St. Joseph in one tomb with the remains of the apostle Simon the Zealot. These were moved here on 27 December 1665"
e. Hebron has the tombs of Abraham, Sarah, Isaac, Rebecca, Jacob, Esau and Leah in the Cave of the Patriarchs but didn't get amended on this Web site when it got inscribed
I am not sure of the best way "out". We have 2 intersecting but not totally overlapping "ideas"
a. Anywhere associated with any of the 12 Apostles including their (supposed/claimed) tombs but also where something significant happened to them
b. Tombs of ANY biblical figures
Do these 2 "ideas" need 2 Connections given the overlap on "tombs" since most of the Apostles Entries are for their tombs? I am inclined to drop the 12 Apostles Connection and ensure that all the tombs are correctly identified in the Tombs one. That would "lose" Jerusalem for the Apostles and Derbent for St Bartholomew (I can find no claimed location for his tomb)
