our house

We bought this house two years ago. I loved the front porch and the way the attic reaches clear around the entire upper half story. You can access the attic from the stairway and my son's closet. I think his room used to just be attic space. And I think the porch was a later addition.
We are trying to find out to which style/period we can restore the house. It was built in 1913 according to our city's public records. I have already stripped the stairs to their original cedar (I think, at least it smelled like it) and stripped and stained some of the living and bedroom trims.
Can anyone help me out?
