On the marriage entry for Nathaniel Hubbard and Elinor Hill, he is described as of 'Barkin' 'Esix'. This was indeed Barking as he and several members of his family were all buried there. I have checked the same registers for baptisms but could not find any for Hubbards. Indeed these generations baptisms I have so far not found, only surmised from the various wills.
Elinor Hill was the daughter of Matthew Hill, a presbyterian minister who resided in Charles County, Maryland. Elinor was bequeathed a large tract of land in Maryland called Poppleton which she handed back to her American brethen - presumably when she settled back in England. This often copied indenture shows the link:

Poppleton still exists, but is now a suburb of Baltimore.
