Question Please translate the title

[Ger]

Anonymous painting of Five Immortals at a game of Go. It looks very old, cut from a larger painting that was in bad shape...
What does the text on the rolled up kakejiku say?
Could it refer to the painter?
Is it possible to estimate the age?

五人物 泉澤囗ヨリ Five people, from Izumisawa -something-

I think its Izumisawa, but that second kanji of the family name could be something else. The red square represents a kanji or kana that I can't figure out. It would be the giver's given name.

 

[Ger]

It would be the giver's given name.

Thanks very much.
It is not the name of the painter but of the person that gave this scroll ?

Yes - it looks to me like it is the name of the person who gave the scroll as a gift.
