the film 1792533 DGS 4379364 is only partially indexed , is there a plan to continue indexing ?
It appears that film 1792533 is, in part or in total) appears to be part of the collection, Luxembourg, Civil Registration, 1796-1941. As the collection description indicates, some records are indexed, including births 1800-1923, marriages 1796-1923, and deaths 1796-1923.
I cannot find any suggestion that the film 1792533 is about to undergo additional indexing.
I would like to draw your attention the FamilySearch Wiki article, Luxembourg, Civil Registration - FamilySearch Historical Records/Known Issues. There are some issues reported here that might help you to find the specific part of this collection that would include your family members.
I hope that this may help.
