IdentificationThe BMD records show there were 2 Samuel Butlers born in Liverpool in the period 1880-1900. One born in 1891 to parents Samuel and Mary and one in 1895 to Samuel and Sarah. The child born in 1891 died the same year so I have assumed the 1895 birth was the correct Samuel.
Deciding which military record was likely to be Samuel's was more tricky. In the CWGC database there were 3 entries for Samuel Butler, 2 entries for Sam Butler and 4 entries for S Butler. I ignored the entries with a middle name as there wasn't one on the memorial.
Of these possibles there didn't seem to be a likely candidate. Cross referencing them with the UK Soldiers died in the Great War database didn't show any connection to Liverpool. It did turn up a record for Samuel Buttler though, from Liverpool. Checking the medal card for this man I found that on the medal card his name was spelled Butler and the address for his next-of-kin was Liverpool. On the evidence I have, it is most likely that this man's name was spelled incorrectly and he is the Samuel Butler from the war memorial.
