As predicted J1-FGC6064 clades have been found related to the Southwestern Caspian populations in Ancient Iranian DNA:

Three new samples from our J1-FGC6064 lineage, the first ancient DNA from our clade, Liarsangbon, Amlash, Gilan Iran_North
Three Parthian samples:
IRN23 and IRN25, a pair of genetically identical/twin individuals from Liarsangbon 200BCE to 100AD - J1-FGC6141 J1-FGC6069
IRN31 also from Liarsangbon 50BCE to 65 AD - J1-FGC6142

J1-FGC6064 clades can be used for a dating method of Indo-European and Iranian languages as a way to date archaeological ramifications and splits of Armenian, Zaza, Parthian, Iranian, Portuguese individuals.
We can have a timeline chronology of the Armenian, Zaza and Iranian languages: "German linguist Jost Gippert has demonstrated that the Zaza language is very closely related to the Parthian language in terms of phonetics, morphology, syntax and lexicon and that it has many words in common with the Parthian language. According to him, the Zaza language may be a residual dialect of the Parthian language that has survived to the present day"

The strong archaeological and linguistic relation and connections between Parthians from Iran and the steppe populations like Alans and Sarmatians mixed populations in the Northern Caucasus and the Northern Caspían steppes.
