Rick,
Please forgive me for acting as a devil's advocate but I make the following observations.
Submitted entries in the IGI may be fairytales in part or all of their details.
There is no Emanuel D given as b. 10 Dec 1594 anywhere in the country according to the IGI. Without verifiable evidence, the details are not trustworthy.
There is a George D submitted birth/christening in 1632 with the location given as "Of Suffolk". If the submitter had found verifiable evidence of the parish's location it would have been given hence the entry is not trustworthy.
The location given against the Nicholas submitted baptism entry is "Drummond" (or Drummond Deery which sounds like a sort of camel - did the LDS submitter have a sense of humour?
) I can find no such British place and even the LDS library Place Search facility gives nothing.
Henry D's baptism is likewise an untrustworthy submitted entry in the IGI.
Further to the above, the LDS film of Sherrington parish church records is in their library catalogue and is given as being in WIL - not that that matters. The Sherrington BT's 1608 - 1880 being the earliest. Had there been earlier records in the WIL record office at Trowbridge, I have no doubt that they would have been filmed.
In conclusion, I recommend that you check the provenance of all your records and any which are submitted IGI entries or found in a another's tree, should be verified by checking reliable contemporaneous documentation such as PR's and BT's.
Regards
Chas
