Hello Lorrie.
There are some patron submissions for both of these families at Gt Stambridge on the IGI online.
However, the Essex Records Office have the Parish Records as well as some Transcripts on fiche for Gt Stambridge.
If you can't get there in person, perhaps the Records Office staff, or someone at the Essex Family History Society (also located in the building), can help with your search.
Regards, Alan.
