Well Spurgeon and Gill held a strong Calvinistic Baptist position but I think they would have been insulted if you called them reformed.

Actually I disagree with you there. Both Spurgeon and Gill held to the 1689 LBCF and I know Spurgeon was very fond of using other confessions such as the WCF.
In fact if you go here you can see a sample of that.
As you probably know there are only minor differences between the WCF and the 1689 LBCF.

However, I will stand corrected if and when you show me evidence that Spurgeon and Gill would be insulted at being called Reformed.
