The family tree of the Sunderland Grecians as far as I can determine goes something like this:
William Grecian married Dorothy Taylor at St John's Church Newcastle 12 march 1778. They had the following children: Margaret b1779 m.Thomas Lewis, William (or Thomas)b.1780,Jane b.1783,Dorothy b.1785,Mary b.1787,William b.1790, Jobson b.1792,and Hephziah b.1797. William (or Thomas) married Mary Moore in 1803 and they had 3 children George b.1803 and died a few days old, Dorothy b.1804 and William b.1806 who married Catherine Rand in 1829. They had 5 children Thomas b.1829, Mary Jane b.1832 m.William Smith, Catherine b.1833 m.John Bond, Margaret Rand b.1835 m.Peter Young, William b.1839 d.1849. I don't know the name of Thomas' wife as this part of the tree is rather vague but as far as I can tell he had children Catherine Rand b.1855 and William Henry b.1856 whose son Thomas married Mary Lodge around 1903 and had the following children: Annie b.1904, Joseph b.1906, Thomas b.1908, Edith b.1910, Elizabeth b.1912 (my mother in law),Lilian b.1914, George b. 1916, Margaret b.1918, John b.1921 and William b. 1925.
If anyone can add to this I would much appreciate it.
