PLUMSTEAD family in Hampshire

[plumline]

I recently put the same request on the Sussex list.
Anyone coming across a PLUMSTEAD event in Hampshire between 1700 and 1800 please let me know. I have only two, one, the marriage of Isaac to Elizabeth 1785 Whitechurch and two, the baptism of their daughter Elizabeth in 1786 also Whitechurch. These are the only records I have of any Plumsteads in Hampshire during that time.
There was an Isaac Plumstead born in Sussex 1740 whom I suspect was the Whitechurch Isaac's grandfather. I am trying to find the missing generation.
Of course they may not have been in Hampshire at all.
Any leads will be most appreciated.
Thanks
Plum
