Terrence, I think this Jane Teare nee Looney below looks likely to be the mother of your Sarah Callow nee Teare b 1846.

She had an illegitimate daughter Christian in 1842, father probably a Mr Kennaugh. Then she had an illegitimate daughter Sarah in 1846, father probably William Teare. Then she married William Teare in 1849 followed by perhaps 7 more children.
