Here is the Merriweather font for your headings. 

Here would be the PT Sans font for your paragraphs. 
Here is Open Sans font for your paragraphs. 

Here is the Baskerville header font.

I think you can also go with a clean font like your logo. All caps for headlines.

This is the same Lato font as above, just not all caps and undercase for your paragraphs. 

Here is the Gilda Display Font. 

Here is the smaller Gilda Display that will go with it. 
And here is the Arial font - simple and modern. 

Here is your current Poppins font, which I really don't mind. 

I've always really liked Georgia.

This is the poppins font that you currently have. I think Georgia and poppins go well together. Georgia for headings, poppins for paragraph text. 

Here is the Garamond font, which adds a softness and professionalism.
