George and Harriet Rainer were in New York in 1820, with George as a 'merchant' - their son John Cragin Rainer (my Rainer great grandfather who died in Melbourne Australia in November 1889 'aged 69') was born there about 1820 - the latter got into the minstrel ('black and white face') business in 1840s and allegedly visited England about 1846 - arrived in Sydney NSW Australia in 1852 from San Francisco with 'Rainer's Original Ethiopian Serenanders').
Although many Rainers (Rayners, Raynors) are recorded in New York since 17th century, my great-great grandparents George Rainer and Harriet de Bowen may not have been US-born;they may have migrated from Europe or the UK in early 19th century. My great grandfather's middle name 'Cragin' was an Irish surname (also Cregan);maybe either his Rainer or De Bowen grandmother had 'Cragin' (or Cregan) as a surname before marriage.
Is anybdy investigating RAINERS in early 19th century New York???
