DESCRIPTION:The assembly history of the Milky Way (MW) is a rapidly evolvi
 ng subject\, with numerous small accretion events and at least one major m
 erger proposed in the MW's history. Accreted alongside these dwarf galaxie
 s are globular clusters (GCs)\, which act as spatially coherent remnants o
 f these past events. Numerous studies have explored the dynamical connecti
 on between accreted MW GCs and their progenitors\, tagging GCs to specific
  merger events in energy\, z-angular momentum space (Myeong 2018\, Myeong 
 2019\, Massari 2019). But as of yet\, no strong chemical "tag" has been fo
 und to support the dynamical associations (Horta 2020). This begs the ques
 tion\, does such a tag exist? If so\, the relatively small range of metall
 icity found within GCs\, coupled with high resolution chemical abundances\
 , could serve as a sharp probe of the chemical evolution history of their 
 host galaxies. In this talk\, I will present results from a high precision
  differential analysis study of the proposed GC siblings\, NGC 362 and NGC
  288 discussing the chemodynamical evidence for and against siblinghood an
 d support for the ratio of [Eu/Mg]  as a chemical link between NGC 362 and
  Gaia-Enceladus-Sausage. Finally\, I will present initial results from a d
 ifferential abundance study of the GC M54 and the Sagittarius dwarf galaxy
 \, highlighting how the only intact GC-progenitor system could set the sca
 le for how similar GCs and their hosts truly are.
