IHS is the central charge of the Jesuit arms, and was a leading symbol of the counter-reformation.

With a sun behind IHS.

Quite. And with three nails. But that is why I specified "central charge".

Further to the use of the IHS monogram, I was inspired to traipse around the local CofI graveyard this afternoon.

Several hundred memorials. From those to 300+ who managed to get themselves killed under the "Illustrious Wellington", down to those of today.

Not a single IHS to be seen, and I walked the entire graveyard.

In the recent times of the 1880s in NZ we have town/city cemeteries and very few church cemeteries.  My gt grandmother would have been classed in NZ as high-ish Anglican.

Her stone does not have the cross in it, only the letters and below that the lilies.  I don't think I have seen the cross in it and if I have I have not thought it was a part of the IHS. 
NZ Anglicans have an empty cross, ie no actual figure to signify 'he is risen'.  RC in NZ have a cross with a sculpture signifying Jesus.

What is the meaning of IHS in Anglican Church?
a contraction derived from the Greek word ΙΗΣΟΥΣ, Jesus, used as a symbol or monogram: later misunderstood as a Latin abbreviation I.H.S. and expanded variously as Iesus Hominum Salvator, Jesus, Savior of Men; In Hoc Signo (Vinces), in this sign (thou shalt conquer); In Hac (Cruce) Salus, in this (cross) salvation.

Well I have learned something.  I think the lack of the cross running through it takes it from rebellious to commonplace in Anglican.  It is often carved in gothic type writing within a circle but no cross.

To return to the original query, I believe 12th February 1739, Old Style (Julian), corresponds to 23rd February, 1740, New Style (Gregorian)
