This worked. Thanks.

Was still redirected to home page because the 'Contact' widget uses the following URL,

http://mydomain.org/blog1.php?disp=msgform&recipient_id=1&redirect_to=http%3A%2F%2Fmydomain.org%2Fblog1.php

This means that somehow the behaviour of the widget needs to be modified. Clearly the behaviour isn't coming from blogs/contact.php since it uses,

// If empty, we will default to return to the same page, but you could put any URL here.
$redirect_to = '';

A possible workaround is to replace the 'Contact' widget with a page link to,

http://mydomain.org/blog1.php?disp=msgform&recipient_id=1

What URL did you use on line 344? This setting overrides any 'redirect_to' params.

It was line 337 for me. Regardless, the URL I used was,

http://mydomain.org/blog1.php?disp=msgform&recipient_id=1

It surprised me that it didn't override the one sent by the Contact widget.

I made a mistake.
Lease the first redirect untouched and edit the one at the bottom

header_redirect(); // exits!

replace with

header_redirect('http://your-address.here'); // exits!

Contact widget still adding the following to the URL,

&redirect_to=http%3A%2F%2Fmydomain.org%2Fblog1.php

...so I've just replaced the widget with another page link (navbar link) to the correct URL).
