Four G3 battlecruisers would likely take admiral names

If all four G3 battlecruisers were built, what names might accompany Nelson?

An admiral-name group is likely, with Duncan, Collingwood, and Jervis as plausible available choices.

The G3s were associated with an admiral naming pattern, making available historic commanders the strongest guide. Duncan and Collingwood had recently become free after older battleships left service, while Jervis offered another prestigious naval name.
