I hope I will not confuse you too much although you may already be aware of this information. But shall add it to the posting in the hope others can shed some further light on the trail for us.
On the LDS site I found: Henry Lowe married abt 1817 Elizabeth Mary Johnson FreeBMD site I found: Elizabeth Sarah Loe married Isaac James Goodlad/Goodland (I think Elizabeth Sarah and Elizabeth Mary Johnson and the same person)- Re census below
LDS site I found: Henry Loe & Elizabeth had a son Francis Robert Loe b. 29th June 1826 ch. 30 Jul 1826 St Leonards, Shoreditch. Francis Robert Loe married Charlotte Harrison

(This is when Elizabeth Sarah Loe marries Isaac Goodla/Goodland in Jun quarter 1850)

CENSUS for Francis J Loe: 1881 Census - 102 Antill Road - London - MDX Francis J Roe 29Shop Stationer - London City Hannah E Roe 29 - Bethnal green Charlotte E Roe 1 - Mile End
CENSUS for Isaac Goodlad: 1861 Census - 2 Middle Row - Whitecross St Isaac Goodlad - 58 - Glass Cutter - Cripplegate Elizabeth Sarah Goodlad 63 - Shoreditch NEXT HOUSE- Living next to them is Susannah Johnson with children Benjamin, Rebecca, Francis, not sure male, Maude & George. I know that Benjamin Johnson married Susannah Loe in June quarter 1842 and is Elizabeth Sarah Loe/Goodlad nee Johnson's daughter and therefore there is likely to be a family link to Elizabeth & Benjamin too.
Family Search has listed: Isaac James Goodlad b. 25 Mar 1803 London ch. 14 Aug 1803 St Giles without, Cripplegate married abt 1850 Elizabeth Mary Johnson b. abt 1800 died 25 th jan 1869.
I think there is an inccorect listing for Isaac Goodlad in the 1871 census and he is the fellow listed as T J Goodlad (father) aged 68 widow Class Cutter - Cripplegate in the home of Maria Thomas in Islington, London and I think the 1881 CENSUS also has an incorrect listing for Isaac as being aged 63 in the District Workhouse Shepherdes Walk in Holborn. He is listed as a Glass Cutter b. Cripplegate so I am pretty sure this is the same Isaac Goodlad. FreeBMD has Isaac Goodlad as dying in Shoreditch aged 82 in 1886.
Now I am about to fossick about for marriages of the children etc and see what connections I can come up with as I think Lowe/Loe are one and the same but the name Loe seems to be the most used and it just seems a big coincidence that there is a middle name of 'Roe'.
