This tree was researched by Gary Keeys (Gretta's dad).
It includes members from the families of Gretta's 8 Gt grandparents: Keeys, Cornwell & Stothart in England. Rankine in Scotland. Kozlowki, Pieczaniek, Huebner and Kruk in Poland.
If I can help you, or you can help me, please get in touch.
PS For the Polish names and places I’ve used a Polish font on my computer but I can’t seem to get it to work here so "¹,æ,ê,³,ñ,ó,œ,¿,Ÿ" should read "a,c,e,l,n,o,s,z,z" (with Polish accents).
