Brennen,
Now you have me looking again at this, havent for ages.
Interesting to see that Carl/Leonard stayed put in the UK, whereas all the remaining Freys went off to New York. I'm fairly certain some of the men were detained during WW1 but all records of German detainees have been destroyed. Alot were shipped off to internment camps on the Isle of Man.
Looking at Carl/Leonards marriage certificate to Marie Stier, I see that George Frey along with Lizzie Volkert are witnesses in 1892.
Nice to see the 1939 register Leonard/Carl with his two daughters, who also get a mention in his will
Regards
Richard.
