If you can't find anything on Alexander WHITE..father was William WHITE, mother was Karoline [unknown surname]....how do you know he was born 1885 in Paisley ? Family records ? Birth Registration of a descendant ? Census information ?
There are many WHITEs born in Scotland and Alexander is quite common as a given name. I will check the INDEXes for Births in Scotland for 1885 and post if there is one born Paisley. Watch this space...... MegG in OKlahoma USA
