Just checked your posting history, as I was wishing I could be more helpful. Are you trying to tie your ancestors Robert McLeod (b 1776) and Fanny Liddle/Little (b 1782) to this William McLeod who dies in San Diego in 1952?
That couple is definitely not this William's parents. They would be dead by the time he was born (whether in 1888 or 1899).
I also see you are trying to find people who have already done a genealogy for this William. So maybe you didn't want volunteer researchers chiming in? FYI most queries on Genforum are answered by volunteers doing original research on behalf of posters - not by descendants who had already accomplished that work.
