my great grandparents came into England from Kovna. I do not know if they were married at the time they were born 1878, 1879 His name was Morris Cohen and her name was Rachel Galinski at least that is what I have been told.  their children were born in Leeds, on my grandmothers birth certificate it states those names. I wish to find documentation of their arrival but I am not sure where I need to go to, to get this info any help will be greatly appreciated.
