In case anyone is interested I have now confirmed the presence of 2 John Hornblow in London around the same time both with wives Elizabeth. The explanation goes thus.
Rev John Hornblow and his wife Elizabeth Young nominated as family 1 because i have done extensive research into his family.
The other John Hornblow and Elizabeth Archer I have not researched beyond him nominated Family 2.
When I began researching 10 or 12 years ago I made an enquiry to Braintree Baptist Church and received from them Rev John Hornblow's obituary and a 1906 article about him.
John Hornblow and Elizabeth Archer were married in 1780 in Westminster and lived in Piccadilly parish where he was a Coal Dealer.
He paid rates in Westminster between 1780 & 1815. This is all verifiable on FindMyPast in this case for Westminster from 1780 onwards until 1815 .
He was a coal dealer in Piccadilly area of London there are dozens of records of his payments and the children attached to this couple were all born in Westminster Piccadilly area.

The Reverend John Hornblow Baptist Minister of Braintree Family 1 left London in 1779 for Braintree.
His Mother Mary Mee was buried St Andrew Anglican Church Halstead 19 Nov 1789 National Burial Index For England & Wales
Jeronimo buried St Andrew Halstead 28 Jan 1797 St Andrew Anglican Church Halstead
His obit stated (Rev)John Hornblow born 1744 came from Halstead & in 1760 was apprenticed in London. In 2017 I found in FindMyPast a 1760 apprentice record showing he was from Halstead , near Braintree son of Jeramiah ( Jeronimo) Hornblow of Halstead , a malster .
The entry in the Haberdashers Court records show that in 1760 John Hornblow was apprenticed to John Rushton of Redcross Square Jewen Street –which is off Aldersgate Street.
He would have been about 15 or 16 years old . John completed his apprenticeship and 1769 . He began taking apprentices in 1772.
The 1775 marriage entry for John Hornblow & Elizabeth Young shows he live in St Alphage parish which is close to St Giles Cripplegate where their first child was born and died of convulsions in 1776. Lived in Cripplegate area by London Wall.
They could not be married in a Baptist church so they chose St Georges in Botolph Lane within the city wall in Botolph Lane close to Pudding Lane which is close to Goodmans Fields where the Young family lived in Mansell Street . They were cabinet makers, furniture makers.
The Young Family were also non conformists as shown by the the registration of their children rather than baptisms. The entry for the family of John More and his wife Rachel Ridley, made in 1756 , shows Rachel born 1749, son Ridley born 1751 then Elizabeth born 1753 and twins Mary & John born 1756.
Their 1st child John was buried in St Giles Cripplegate - Maidenhead Court in the close to AlderSgate Street. He later moved his workshop to Phillips lane near St Alphage 1778 John still working as a looking Glass Frame Maker .
Other children must have been born and died young between 1777-1782 - a 5 year period, for they were commented upon by Dr Perrott in Braintree in 1779 who remarked on the size of Johns family and the smallness of his purse.
1779 John’s was ordained on 15th July 1779 and given the Braintree ministry moved to Braintree, Essex

There is an Ebenezer son of John Hornblow deceased apprenticed by patrimony to Ebenezer Hornblow silversmith in Southwark in 1820. However if boys were apprenticed at 12 to 15 then he would have been born about 1805 which makes him an unlikely son of Rev John for, although his wife Elizabeth Young was 10 years her husbands junior, she would have been 52 in 1805.
An Ebenezer Hornblow did witness the 2nd marriage of Sarah Hornblow ( Moore) when she married John Cadle in Deptford in 1816.
