The Garden Tomb was suggested to be Golgotha by who first? No. Update your information please. It was well known by the post-Reformers to be the very place you may suggest to be first proposed by Robinson? Or Thenius following him? Not so. Already in 1595. See this.

John Speed was the famous cartographer for drawing a map of Canaan which was included in the KJV of 1611. He drew it in 1595.

So, I conclude that the Jerusalem map dates to 1595.

The following information in Wikipaedia can now be updated or corrected with more secure information that the concept that the hill 200 meters from the Damascus Gate was also considered by the Post-Reformation Scholars from Westminster and Oxford and Cambridge to be Golgotha. The identification dates to 1595 but included in the 1611 KJV original.

Otto Thenius was not the first to suggest this location to be Golgotha. Correct Wikipaedia here. Thanks.

“In 1842, heavily relying on Robinson's research, Otto Thenius, a German theologian and bible scholar from Dresden, was the first to publish a proposal that the rocky knoll north of Damascus Gate, which, as Thenius noticed, resembled a skull, was the biblical Golgotha. The site he suggested contains a few natural cavities as well as a man-made cave, which Christians call Jeremiah's Grotto. Thenius went so far as to suggest that Jeremiah's Grotto was in fact the tomb of Christ.[12][20]”

Thenius, Otto (1842). "Golgatha et Sanctum Sepulchrum" (in Latin). In Zeitschrift für die historische Theologie.

Thenius was thus not the first to suggest that Golgotha is situated at that hill. John Speed did it in 1595.
