“In July 1776 there were six Northern, six Southern and one “keystone” state.”

You are going pretty far afield to claim that Pennsylvania was not a Northern state.

I would even contest your statement that Delaware was a Southern state if I didn't happen to know about the famous 1st, 2nd, and 3rd Delaware State Confederate cavalry regiments; and the 14th, 18th, and 23rd Delaware State Confederate infantry regiments; and so forth and so on.

In fact, Pennsylvania normally voted with Southern Democrats, then as now only rarely switching sides to support the Whig or Republican candidate for president.
One of those rare years when Pennsylvania voted Republican was 1860, another 2016.

Indeed, while Delaware had very few slaves in 1860 (90+% were already freed), it was one of the few states where slavery was still lawful when the 13th Amendment was ratified in 1865.
Delaware-ians did free all their slaves after the war, but refused to ratify the 13th, 14th & 15th amendments until 1901.

As for those alleged Confederate regiments from Delaware:

"While most Delaware citizens who fought in the war served in the regiments of the state, some served in companies on the Confederate side in Maryland and Virginia Regiments.
Delaware is notable for being the only slave state from which no Confederate regiments or militia groups were assembled."
