polish cheesecake-need explanation & recipe

My grandmother use to make a cheese cake type of pie, which she and my relatives called "Kolach". I may be spelling that wrong, but that is how it sounded. When I did a search online, all I come up with is polish cheese cake or "sernik babci". The pictures look exactly like this pie she use to make. Why did she call it "kolach" ?

Does anyone have an easy version of this recipe? Recipes with variations?

We found this recipe
Kolach
1/2 pressed farmers cheese-it doesn't say cup or other measurement
2 or 3 eggs
3/4 to 1 cup sugar
1/2 lemon-doesn't specify if it's juice and if measured by cups
1/4 cup milk
rasins if desired
beat egs and sugar, add crumbled cheese, the lemon juice and milk, add rasins, bake 350 40 to 50 mins.

It mentions no crust??

I found this link earlier,

I am still confused, scroll until you see the square dish with the braided top, this website calls it "sernik" but it's square, other pics on website are round.

My cousin remembers a square desert:

my sister and I remember a round pie like desert:

I think "sernik" and "kolacz" are very similiar, but different.

sernik, a pie, with a crumb dough you put down as the base, then add cheese filling, and nothing else is added on top?

and

kolacz, a sqaure dish with a heavier bread with a cheese filling placed on top, then more dough braded on top?

I found a recipe in my polish traditions book. It is called: Serowiec or Cottage Cheese Cake and another recipe called Cream Cheese cake with a sour cream topping variation. Each of them has the polish title "serowiec".

The first has a graham cracker crust and the cheese used is cottage cheese, and you use a round cake pan, the second has a pastry crust with cream cheese for the cheese, and then has the sour cream variation and spring form pan.

I think this is what I was remembering. So I am giving it a go for Easter.

Kolach
1/2 pressed farmers cheese-it doesn't say cup or other measurement (I think it is 1/2 kg = about pound)
2 or 3 eggs
3/4 to 1 cup sugar
1/2 lemon-doesn't specify if it's juice and if measured by cups (guessing juice but you can also add zest?)
1/4 cup milk
rasins if desired

In a mood for thinking about food. Cheesecake, yummy.
