Yehoshua or Yeshaya Lichtenstien?

Hi I added a profile photo taken from the above link, after I got a tip that this was a son of Baruch Bendit ben R' Hillel Kolomea'r. the only confusion on him is whether his name was Yehoshua or Yeshaya, or were they two sons of his.
Yoel

Its Yeshaya. My mistake.
