OK, Pete
1. So Michael PORTER & Margaret LEMAN are now out of the picture. We will forget about them.
2. As far as the IGI is concerned, there are two sorts of entries
(a)
extracted entries (from church records and statutory registers) which were completed under the controlled extraction program of the Latter Day Saints, and
(b)
submissions made by members of the LDS.
The
extracted entries are reliable (though, of course, there could always be transcription errors - the film of the original register should be consulted if you want to be certain).
The
submitted entries, on the other hand, need to be treated with great care - some are reliable, some are not (indeed, some are nothing more than wild guesses). Always be particularly suspicious about
submitted entries which give dates and locations enclosed between < >, or with 'about' or 'of'.
3. The IGI entry for the marriage of
*Henry HAWKES & Frances PORTER, 26 Dec 1796, St Dunstan Stepney
is an
extracted entry i.e. reliable.
The IGI entries for the birth of Henry HAWKES and the birth of Frances PORTER are
submitted entries and have dates and locations between < >. I would
ignore them altogether.
The IGI entries for children of a Henry HAWKES & a Frances are also
extracted entries (we are assuming - with a fair degree of confidence - that there was only one couple of these names having children in the area around the right time).
The children are:
*Henry James HAWKE (sic), b 1800, St George in the East, Stepney
*John Thos. HAWKES, bap 1802, St George in the East, Stepney
*Sarah HAWKES, b 1805, St George in the East, Stepney
*Elizabeth Frances HAWKES, b 1807, St George in the East, Stepney
*Henry HAWKES, b 1809, St George in the East, Stepney (presumably the first Henry had not survived)
*Caroline HAWKES, b 1813, St Matthew, Bethnal Green
*Hannah HAWKES, bap 1815, St Mary Whitechapel, Stepney
*Joseph HAWKES, b 1820, St Matthew, Bethnal Green
4. We are then assuming (pretty confidently) that the above Joseph HAWKES b 1820 is the same as the Joseph HAWKES who married Catherine BALDWIN.
The entry for that marriage in the IGI is an
extracted entry:
*Joseph HAWKES married Catherine BALDWIN, 10 Jun 1845, St Leonard, Shoreditch
We also find that marriage on FreeBMD - Joseph HAWKES, marriage, June quarter 1875, Shoreditch, Volume 2, Page 437; a Catherine BALDWIN is on the same page.
We think that Catherine is probably the birth in the following
extracted IGI entry:
*Catherine BALDWIN, b 1818, St Dunstan Stepney, parents Samuel BALDWIN & Mary.
There's an
extracted entry for an 1818 marriage of a Samuel BALDWIN & a Mary HOLMES who might be Catherine's parents.
There's also an
extracted entry for a 1789 marriage of a Samuel BALDWIN & a Mary TRIPP at St Dunstan Stepney, and
extracted entries for children to a Samuel BALDWIN & a Mary in the East London area between 1792 and 1800 -
perhaps this might have been a first marriage of Catherine's father.
We also think that Mary (HOLMES) BALDWIN is probably the (re-married) Mary WILLOUGHBY who, with her 9yo son John, is with Joseph HAWKES and Catherine (BALDWIN) in the 1851 census.
It would be necessary to obtain the 1845 marriage certificate of Joseph HAWKES & Catherine BALDWIN to make sure that the names of their fathers were Henry and Samuel respectively.
5. Presumably you still wish to know birth/baptism details for Frances PORTER (and Henry HAWKES - or do you have them?)
A Frances HAWKES (probably the Frances PORTER who married HAWKES) is listed in the 1841 census (remember ages were supposed to be rounded down to the nearest 5 and relationships were not given) as aged 65 and born in the county. This gives a birthdate of ca 1772-1776.
From FreeBMD, a Frances HAWKES died June quarter 1849 in Bethnal Green. Unfortunately, if this is your Frances, it means she didn't survive until the 1851 census (where more precise places of birth are given).
Her birth/baptism
might be one of the extracted entries in the IGI or it might not appear at all (apart from the quite unreliable
submitted entry)

Similarly for Henry HAWKE(S).
