Kamons and Clans

The kamon with four miyeshi in a circle belongs to which Japanese clan? It looks like Matsumae clan's mon, but has a dot in each diamond. Based on my search the kamon itself is called "Maruni Sumitate Yotsumeyui"? I saw it on a t-shirt, but can't find much info about it online. Your help is appreciated.

No one knows? :(

I'm not expert though...
Yes, Matsumae clan's "maru ni waribishi" has no eyes as you said.

According to Wikipedia, "maru ni sumitate yotsumeyui" was used by Teramura clan at least.

Yes!! It is the second one!! :D
Thank you so much! You are the best!
Unfortunately I can't read kanji, and google translate decided not to cooperate either. Keeps saying " Bad request". I don't see how it is "bad". Like, would Santa not visit that site because Rudolf can't read kanji either and there is a risk of getting lost in the world of beautiful lines? Anyways, I'll try more, specially since searching ["Teramura" clan] is showing me no related result. The universe is trying to prevent me from finding out, which is making me more eager. lol
Thanks again! :)

So, it doesn't translate the wiki page, but does ridiculously translate it part by part if I copy/paste. Not really understandable, but better than nothing. Regardless, even if I have to start learning kanji from ground zero, I am going to find out all about the history of that clan as if I was one of them! lol My motivation level is piercing the roof at the moment. :P

Google translate works for me when I translate using this URL http://ja.wikipedia.org/wiki/������

I don't know why it doesn't work for me then. The section by section translation was also annoying as hell. But, based on the info on that page, I just searched "Uda Genji Sasaki" and took it from there.

How about this, though you found the key word already.

Somehow, that worked!? Yaaaaay! :D
Many thanks for your continuous help, ajapaneseboy! I really appreciate it. :)
