In 1871 Ancestry has made a real mess of the transcript, but correctly CRELLIN:
Name Age
John Cullin 50
Elizth Cullin 48
Iran Cullin 16 - [should be John]
Anne Cullin 13 - [this is odd. The same age as given for Elizabeth in 1861, where Ann was a year older.]
Rebecca Cullin 10

Rebecca CRELLIN is a servant aged 28 in Peel in 1891.
