the village is not Sprile for this JOACHIMSTHALERs but Spule.
Thaler, Anton Joachins Spule 20 1872 1892 He too arrived NY Ellis Island.
2 small villages named Spule in CZ; one by Klatovy [Plzensky kraj] and Prachatice [Jihocesky kraj]
JOACHIMSTHALER still in Spule's phone bookhttp://seznam.1188.cz/s?q=joachimsthaler
So than we have 2 different family names.
If we go by the CZ's phone book we have
JACHYMSTAL in Stredocesky and Ustecky
JACHIMSTALOVA in Ustecky
The clues as to the Vilmuze/Vlimuze has to be in some church document in US. Have you seen the tombstone?
Was the obituary in English?
