Just in case you find that Frederick's father was James, here is a marriage record which I might lose in the meantime.
James Clarke, born 1816, aged 35, father John Clarke
married Mary Potter born 1821,aged 30, father Henry Potter
on 10 June 1851 in Glenavy, Antrim.
This COULD BE Frederick's parents, but might be a red herring, so keep it for the moment.
