Moses Hyam or Hyam Moses - name reversal in early 19th century #unitedkingdom
I'm trying to establish the full names of the parents of Benjamin Louis HYAM, born about 1817 in London, died 1870 in Swansea
In the censuses of 1841 and 1851, Benjamin was recorded with his mother, Sarah, and her second husband, Cosman COHEN.
On 19th November 1856, he married Lucy, the daughter of Jacob HADIDA in London's Great Synagogue. The transcribed marriage record (https://synagoguescribes.com/blog/person-details/?value=8176) shows that his father's Hebrew name was Chaim. This matches the inscription on his gravestone (https://www.jewishgen.org/jcr-uk/Cemeteries/Swansea_Cemeteries/Burial_Townhill_A_293.htm) which gives his full name as Binyamin Yehuda ben Chayim. However, according to the 1851 Anglo-Jewry, his father was Moses HYAM (https://www.jewishgen.org/databases/c1851.php?rec=C1851C_0019985).
Now, on 3rd June 1812, a Hyam MOSES (Chayim ben Mosheh Shvab) married Sarah LEVY (Sarah bat Yehuda-Leib) in the Great Synagogue. See here https://synagoguescribes.com/blog/person-details/?value=2273
My question is whether it is likely that Hyam MOSES reversed his names and became known as Moses HYAM, with his wife, two sons and future generations bearing the surname HYAM?
