Also some added info for you both.
I was interested by Abia Butfoys marriage at St George in the East Church:
"Ann Allar and Abia Butfoy, married 11 Aug 1765 by William Dubordine, Curate, Witnesses John Corson and Elizabeth Westfield"
I noticed, (as well as the vicar who married them clearly being also of French or Huguenot Stock!), the wifes surname might also suggest another Huguenot family.
I have had a look into her and think this is so.
Ann Allar, baptised 25 Oct 1748 St Leonards, Shoreditch.
Parents William Allar and Violetta Ward (Married 12 April 1732 St Dunstans Stepney)
Other children:
Mary Allar baptised 1735 St Dunstans Stepney
William Allar baptised 1740 St Dunstans Stepney
Mary Allar, baptised 1743 St Marys Whitechapel
Sarah Allar baptised 1753 St Matthews Bethnal Green
William, the father, I believe was originally baptised in the French Church as 'Guillaume Allar" to an Anthoine Allar and his wife Marie Lord.
They were married 2 Nov 1703 at St Dunstans, Stepney, and had the following children including Guilliame baptised at the French Church Threadneedle Street:
Guilliame Allar son of Anton Alar, Weaver, and Marie his wife in Fleet Street, Stepney Parish. Godparents Nicholas Bertran and Madeliane Faucon. Feb 17 1706
Elie Alar and Marie Alar, son and daughter of Anthoine Alar and Marie, Godparents Elie Alar and Maire his wife, and for the daughter, Antoine Allar and Marie his wife on Oct 26 1712, born 20th same month.
Sarah Allar, daughter of Antoine Allar and Marie his wife Godparents Isaac and Marie Allar, March 27 1715
Ester Allar, daughter of Antoine Allar and Marie his wife. Godparents Jean Baptiste Cabile and Ester Podextre
I would think the Elie and Isaac Allar who appear as godparents are most likely siblings of Antoine. Anthoine and Isaac at least appear in the records of the Threadneedle Street London Church joining from Canterbury around same time:
Antoine Alard testimony from the Huguenot Church of Canterbury 31 Dec 1704
Isaac Alar and wife testimony from the Huguenot Church of Canterbury 30 Sep 1705
I don't have the Canterbury registers but looking purely at the IGI, Isaac (and his wife Mary Six) had at least two children baptised there, a daughter Sara in 1696 and a son Isaac in June 1701 (His godfather in canterbury was Anthoine Allar. He later joined the Threadneedle Street Church London as a full adult member aged 19 in 1720, and married not long after having several children baptised there, with Antoine Allar standing as godfather there also ).
I believe the parents of Isaac (sr), Elie and Antoine are most likely a Guillaume Allar and his wife Margeuritte.
They appear in London on 4 April 1674, when they joined with a testimonal from the Huguenot Church in Liede, Holland. They then had two children baptised not in London, but at the Huguenot Church in Canterbury, Kent, a daughter Lea in 1676 and another Daughter Judith (1678). They then turn up again in London rejoining Threadneedle on 9 July 1679, with a testimonal from the Huguenot Church in Canterbury.
Since they clearly moved around a bit, I wonder whether the three sons were born whilst they were over in Holland? A Judith Allar appears alongside Anthoine, Elie and Isaac, in the church records in London after 1703, so might well be the Judith baptised above in Canterbury, who I propose as their sister. It also makes sense Anthoine calling his first son Guilluame (William) if it was indeed his fathers name.
Guilluame, the (probable) father, was himself probably born in England as their is this baptism at the Huguenot Church in Kent:
Guillame Allar, son of Guillame Allar and Jean Soteau, baptised 11 March 1654 Huguenot and Waloon Church Canterbury.
I cannot trace them back any further than this with certainty.
There is an Andreas Allard, born in Leyden, Holland, who was granted denisation in Britian by King James I on June 22 1614. Whether he was related I do not know.
There is however, another, small but very intriguing clue to the possible family origin in the records of the French Hospital of London. In 1932 a female patient with the surname Lee applied and was admitted to the Hospital, claiming French decent through her grandfather one John Allard. She stated (and proved with documents) that he was decended from one Claud Alard, who was baptised in Canterburys Huguenot Church in 1590.
If this is right, this would give you both roots, through Ann Allar, back to the early communites of Huguenots and Walloons in England.
