Hi Dort,
If you have the burial information from WTC you should know what year Richard was buried. (Though I suspect both of these men were buried at West Terrace)
I suspect the Richard LLOYD who died in 1907 is the one who arrived in 1855 but is he your ancestor? I doubt it.
He appears several times in the destitute asylum records in 1903-1906
1903 aged 65 arrived aboard BUCEPHULUS been in colony 48 years residence Pt Augusta
1905 aged 67 arrived aboard BUCEPHULUS been in colony 50 years residence Destitute Asylum
1905 aged 67 arrived aboard BUCEPHULUS been in colony 50 years residence Destitute Asylum
1906 aged 68 arrived aboard BUCEPHULUS been in colony 51 years residence C/O DR Bickle North Terrace.
The man who died in 1919 is listed as married which fits with your man.
Cheers Kris
