I'm trying to trace the siblings of my g-g g'father William Thomas Moore (b. 1837 Maughold). These are the children of William Moore snr (b. Maughold 1798, d Maughold 1850 aged 52) and his wife Ann Maddrell (b. Lonan 1814, d. Maughold 1903 as Ann Jelly).

The siblings that I am looking for are:
Margaret Moore b. 1839
Mary Ann Moore b. 1841
Ann Moore b. 1844
Thomas Moore b. 1846
All were born in Maughold. Ann & Thomas were living with Ann Maddrell and her second husband William Jelly at the time of the 1861 census.

Looking at the IGI, I have a few leads on marriages in Maughold that may be for these siblings but am hoping to either confirm or deny these. Possible options are:

Margaret
Thomas McKneale 24 Oct 1863 Maughold
Harry Harcomb 3 Nov 1865 Maughold
Henry Costain 17 Jun 1866 Maughold

Ann
James Gelling 8 May 1862 Maughold

Thomas
Sarah Bourdon 13 July 1867 Maughold
Jane Dougherty 29 May 1869 Maughold
Jane Stevenson 3 Aug 1872 Maughold

I haven't found any possible marriages for Mary Ann. Of course its possible that they never married or marriages occurred outside Maughold.

Any help would be much appreciated to confirm or rule out these. Likewise, any other clues as to what happened to the siblings would be great.

Thanks for your help
