Have struggled endlessly with the Browns.
My Grt Grt Grt Gran was Mary Brown born circa 1830 in the Lincolnshire area, and married Thomas Smith (s/o William Smith & Ann Elliott who died at Horncastle). Mary Brown ended her days in Horncastle in 1915, being at the time of Waring St, by the Wong, which was where the Horse Fairs were held. I know they married at Wrawby by Brigg and that her fathers name was Thomas.
The only other family of travelling Romanies I have found in the area with the name Brown include the Francis Brown/Rosetta Smith families.
Francis and Rosetta appear to have had the following children by surnames Smith or Brown:
Violet Smith 1826 Ruskington d/o Rosetta - married Sidney Gray
Eliza Smith 1828 Redmile d/o Francis & Rosetta - married Nathaniel Smith
Christopher Smith b.1834 Fulbeck Lincs s/o Francis & Rosetta
Harriet Brown b.1836 Blyborough Lincs married Joshua Gray aka Mobbs
Charles Brown b.1839Laceby (believed to be the man known as Charles Dalton Brown) s/o Francis & Rosetta
Adillarania/Dillerany Brown b.1843 Harmston married Anyan Hewitt 1862
Maria Brown b.1845 Ingham Lincs
William Brown b.1849 Tealby Lincs
