Question

does anyone know where the last name olmo stem from. And does anyoen know of a free site that is a worthwhile research tool of family trees ? I have tried many but they are all scams or cost lots of money.

Answer 1

You couldn't google it?  I found this in 3 seconds:

Italian (mainly Tuscany and northern Italy) and Spanish: from olmo ‘elm’, Latin ulmus, topographic name for someone who lived by a conspicuous elm tree, or a habitational name from a place named Olmo, from the same word.

Answer 2

it stems from tuscany and spain.

I would check all surname history sites.
