Help with Mei identification

[Iwo87]

Hi there!

I was hoping to get a little help with this signature on my Wakizashi. Apologies it’s hard to read so really challenging to take quality pics. 
1) I was told it’s 

近江大掾藤原兼定

Ōmi Daijō Fujiwara Kanesada

2) late 1600s 

3) I was told the Nakago was burnt in a fire

4) the pics w 3 images the middle Mei is from a papered Wakizashi and the 2 outside images are from my study blade with my attempt to make it more legible.

 

Thanks for any input or help!
