I'm sorry,but I can't find any information in my files that positively link with your family.The following are the date, place and spouse's of all the James Lintott marriages in the IGI for England relevant to your time period.
17 Aug 1802 Saint Lawrence Pountney, London, London, EnglandSarah JEFFREYS; 19 Jan 1806 Saint Lawrence Pountney, London, London, EnglandElizabeth JEFFERYS; 29 Jan 1807 Terwick, Sussex, EnglandMary EADE; 19 Dec 1808 Saint Nicholas, Rochester, Kent, EnglandJane PRICE; 12 Dec 1814 Saint Marys, Portsea, Hampshire, EnglandAnn JENNINGS; 19 May 1816 Chiddingfold, Surrey, EnglandMary EDWARDS; 20 Jan 1818 Walberton, Sussex, EnglandJane BIRCH; 3 Aug 1822 Saint Leonards, Shoreditch, London, EnglandSarah WHITTENBURY; 6 May 1828 Saint Martin In The Fields, Westminster, London, EnglandMary Ann THOMAS; 6 Aug 1832 Saint Martin In The Fields, Westminster, London, EnglandMary SIDWELL; 28 Jul 1835 Chiddingfold, Surrey, EnglandMary DENYER; 23 Sep 1835 Ockley, Surrey, EnglandSarah ELLIS; 10 Oct 1835 Terwick, Sussex, EnglandAnn WITHAL; 21 Nov 1840 Chiddingfold, Surrey, EnglandMary CARTER;
The two James Lintott's who married Sarah and Elizabeth Jefferys in 1802 and 1806 in London may be a good choice for followup as would be the James who married Sarah Whittenbury in 1822.The 1828 and 1832 marriages would also fit in for your Ann being born at that time.
Search the IGI index for James Lintott and the relevant year to find the sources and films that are available.
I hope you can make a connection.I'll post this to Genforum in case someone else can add to it.
