Aargh! Sorry! Why did I type Eleanor?? I think I must have misread my scribbled "Eliza w m". What I SHOULD have put was:

1871 Census:
41 Old Laxey Rd, Laxey, Lonan (RG10/5774 f.38 p.32 sch.171)
William Crowe - h - m - 31 - Mines lead miner - born Lonan [1840]
ELIZA Crowe - w - m - 27 - Lonan [1844]
James - s - un - 9 - scholar - Lonan [1862]
Alice - d - 7 - Lonan [1864]
Elizabeth - d - 6 - Lonan [1865]
Ann - d - 5 - Lonan [1866]
Eliza - d - 3 - Lonan [1868]
William - s - 2 - Lonan [1869]
Catherin - d - 5mo. - Lonan [1870]

The name Eleanor Crowe hasn't figured at all yet, not in the 1871 census or the IGI, and Emily only in the unusual birth entry for 1879 in the IGI.

I found her siblings by typing in only the names of the parents, "William Crowe & Eliza", selecting Births/Christenings, 1882 +/- 20 years, British Isles, Isle of Man.

Sorry for the slip of the brain.
