Hi
I'm struggling too.
I can see Gabrielle Lorraine Le Roy Alien ID card 1941 Deauville St Lukes born 21.8.1923
Which is available to purchase from Jersey
https://catalogue.jerseyheritage.org/collection-search/?si_elastic_detail=archive_110046899Obviosly haven't done that but there may be more Info on that.
At the same Address is
Charles Louis Le Roy born 28 July 1925 .presumably a brother.
https://catalogue.jerseyheritage.org/collection-search/?si_elastic_detail=archive_110046898He died at St Peter 26 Dec 2017 as Charles Auguste Louis Le Roy.
If we take that as a starting point
Charles Louis Auguste Le Roy born 1863 basket maker married Marie Louise Le Begue age 24 at St Hellier .Father Laurens Francis Le Roy poulterier
In 1901 they are at St Peter Port Guernsey
Charles Le Roy 35 basket maker France
Marie 30
Anselmo 13
Bertha 11
Louise 9
1911 St Hellier
Marie widow 49
Anselmo 22 (died 14.6.1929 New St St Helier)
Charles 9
Frederick 7.
In 1921 there is only one family who could be yours in Jersey (forgive me for not putting the full details but I'm worried about copyright).
Florence Maude Le Roy married 27
Florence May 3
There is no father/husband and I can't find a marriage but I'm willing to bet he is one of the sons of Charles Louis Auguste Le Roy and Marie Louise Le Begume.
Hopefully the ID cards from WWII will give you more info and enable you to check the earlier generations.
ps there are also Alien Reg cards for Anselm and Marie Louise with nice photos on the same website. And it turns out Anselme was the husband of Florence Maude and father of Florence May.
