Modifying H1 on Home Page – Hello Blush

Hi,
I would like to replace the font that is used for H1 on my website. I have downloaded a font replacer, as recommended in another thread here. The problem is, H1 seems to be different throughout the homepage (I’m using HelloBlush). In the first section of the page, it is the cursive font, but lower down the page, it seems to also represent the Fiona font. 
 
Is there a way that I can use another font for H1 *just* in the upper areas of the home page? I’ve tried multiple techniques but none have worked. Please advise. 
 
Thanks, 
Siobhan
