Although their was apparently no objection to the merge, since it is still public, "anyone can view all the information on a Public profile. However, you still need to be in the Trusted List to add or change information." That is a quote from a click on the green padlock, seemingly a contradiction with the merge instruction.
Also, with so little information, it is entirely possible that it is a different Louis Gasner. Surely that name would appear numerous times in Ige in the years since 1574. I would not continue the merge unless the profile manager (who has been inactive since September 2017) confirms that her profile was intended to be the same Louis Gasnier as yours (which is unsourced as well).
