Isaac Leet Ancestors in England

I am trying to establish with a reasonable degree of certainty the English ancestors of Isaac Leet, the early immigrant to New Jersey and ancestor to Daniel Leet.  Other entries in this blog provide background to my quest.  I've been reading James Oliver Goldsborough's book "Misfortunes of Wealth," which includes information about (Major) Daniel Leet and his descendants.  Page 289 shows a picture of Newington, which was Eliza Leet (Shields) house.

In "The Family Face," Michael Leete speculates that the immediate English ancestor to Isaac Leet was Gregory Leete (1627-1672) of Badby.

I've just started to explore the English church records recently made available through Ancestry.com.  I found this record.

Name:	Margret Leete
Marriage Date:	Feb 1639
Parish:	St Mary, Newington
County:	Surrey
Borough:	Southwark
Spouse:	George Benor
Record Type:	Marriage
Register Type:	Parish Register

Could this be a connection?  I didn't have time to research Gregory of Badby.

BUT... for those Daniel Leet fans out there, was the house Newington named after the place or road Newington in England?   (There is a Newington Road just a few miles from Badby village.)
