If you go to iomfhs.im and follow research to Lawsons BMD Micro Site then dissenter baptisms you will see some of the family.

1851 in Liverpool at Court 28 Hornby St.

John Brennan 50 Brasser? Ireland
Clara 52 wife Ireland
Robert 26 Brasser ? Isle of Man
Catherine 24 wife Macclesfield
Mary 23 Isle of Man
Susan 20 Isle of Man
Sarah 2 Grand Daughter Liverpool
Eleanor 2 weeks Grand Daughter Liverpool

John may have married again but I suspect that Ellen was misread for Clara.
