Yes, that is his WWI Draft card.
I haven't been able to find a definite arrival manifest - I've searched for both GIL and GILL and only come up with one that *may* be him (all the others I've ruled out because the age at arrival wouldve been way off from his birth date). This manifest has Andrew listed as age 16 (he wouldve been 18 in 1906) and going to Port Richmond, PA to meet his stepfather. I'm taking the manifest with a grain of salt as there's no evidence that this is truly my Andrew.
Thank you for the help with Januf/Janow!
