[1][2] Parker married Frances Mary Hoskyns on 7 February 1832, at St Lawrence's Church, Appleton (then in Berkshire, now in Oxfordshire).

[1][2] In recognition of his work, Parker was decorated by King Victor Emmanuel II of Italy and received a medal from Pope Pius IX.

[1] In Italy, one of Parker's principal projects was to compose an archive collection of photographs of the city's greatest monuments from the Renaissance era onwards.

Employing local photographers the collection recorded not only Rome's greatest building and works but also detailed scenes of the late 19th-century archaeological excavations.

In 1893 the entire archive perished in a fire at the Palazzo Della Porta Negroni Caffarelli depriving modern archeologists of an invaluable source of material.
