Thanks, I have used the above site, but even though I know from US records that my ggGrandfather was born in 1829, I have no clue of the month and day. That makes finding him impossible.
Not if you have other info that could be used to verify if it is right person... based on his parents/siblings, family info, and maybe ship logs, if they came to America.
