"Ive failed to find Marriage certificate for Thomas La**** and Ellen Thomas,at Bristol in 1835: which I hoped would yield at least one name for his parents."
I've posted elsewhere about the marriage - before 1837 and civil registration there will be no certificate, only the Parish register entry which will not name parents; it will have two witnesses (normally) but these may not even be relatives. There seems to be no entry on the BAFHS CDs of baptisms for Thomas, so you may need to look at parishes near the city but not part of it. Most PRs for south Gloucestershire are at Bristol RO, but not all. If you contact Bristol RO they can send you a copy of the marriage (for a charge),
