I tried your e-mail but it doesn't seem to be active. My grandfather William J Gilkes was your father's older brother. William Gilkes was born in 1889 in Passaic NJ. Not sure when he moved to Fl. William and Peter's father is Thomas G Gilkes, born in Barbados abt 1860-1864. Their mother is Nellie Brown from Holland. I don't have any info on your father. I believe Thomas G Gilkes' mother is Catherine Elizabeth Gilkes ( don't have a father's name )and Thomas G Gilkes has a brother Joseph Bruce Gilkes born abt 1851 in Barbados. Thomas, Joseph and their mother came to NJ from Barbados abt 1800. This information is from familysearch.org and ancestry. Your father also had brothers Thomas and Edward. Also, sisters Nellie and Eva.
