I wonder what recommendations you may have for apps to load up and navigate lat long positions. What recommendations do you have for a compass app that allows for entering historic declination? Thanks for your help
I can't help with the application question, I'm still in the Dark Ages when it comes to that high tech stuff.
I am however curious about what you mean by "app that allows for entering historic declination."

I would guess that with Google Maps, or Bing, you could type in a Lat & Long on your smartphone (I know I can do that on a home pc).
For the declination you could bookmark this Historic Declination page and add or subtract the period declination from your current heading, provided you have a compass app on your phone.
MapIt for the lat long functionallity.
AndroiTS Compass gives a real magnetic declination base on your location.
I've had alot of fun with this: https://play.google.com/store/apps/details?id=com.mictale.gpsessentials&hl=en 🙂

i WANT TO BE ABLE TO ENTER THE DECLINATION AS IT IS SHOWN ON A MAP. iT SEEMS THAT MANY APPS WILL CALC A CURRENT DECLINATION AND ADJUST THE NEEDLE ACCORDINGLY.

Well, I asked because IF you want to "follow" a line run in 1880 using a declination/variation of [say] 18å¡ East, then you do NOT want to use that declination TODAY!
But I'm sure you already knew that.

Theodolite HD almost does everything you are looking for.
It does lat/long, as well as has a compass feature with the option of magnetic or true. The one problem with taking declination adjustment from old maps is that magnetic north changes over time.
To do this accurately, there is an online web page called "magnetic declination calculator".
Best of luck.
