If you are tired of looking for your own ancestor--care to look for a couple of mine please

Henry Thomas Larmuth/Larmouth b 1832 Finsbury London--son of
Alfred William & Jane nee Wright.
According to Family Search he married twice--Martha in 1852 in London and Maria in London in 1895. There is a probate dated 1915 leaving a small sum to Maria.
1851 Thomas is with parents
1861 a visitor [Married] to married sister Jane Ann Sacker
1871 with wife Martha who appears [from census] to be 15 years the elder and b in Bedfordshire. Plus Harriett -daughter-- b 1856 in Kent
1881 Still with Martha in Paddington[FindMyPast shows name as
Harmouth
1891 Still with Martha-Lambeth
1901 Now with Maria in Battersea-she appears as 15 years younger than him.
1911 With Maria in Clapton.
I simply cannot find either Martha or daughter Harriett in the 1861 and run out of where else to look!!FindMyPast-- Ancestry --census --tried Google with all the names--censuses with various surname spellings -
Also --although there is apparently 2 marriages in london they don't [or i can't find them!!} appear in the Ancestry 1754-1921 marriages.
Both marriages for Thomas henry are in the 1837 marriages but of course no partner's name.
I have been hunting down the Larmouth/Larmuth family for some time now and am trying to tidy up loose ends. poli
