External content in wordpress template

Hi,

I have searched through the forum and also google and tried a few different suggestions with no luck so far.

My issue is I have a family blog, using WordPress, and have some external HTML generated by GRAMPS. I uploaded the HTML created by GRAMPS to the server, and now want to be able to present that HTML so it looks uniform with the rest of the blog.

So, any page or link from the GRAMPS html, i would like all of it presented as part of the wordpress template so it looks like its all uniform.

Can anyone point me to a howto or article on how to do this?

Thanks!
