For persons living now in any area you can consult any number of internet people-finder sites, such as those called 'white pages'.

Genealogical sites are not well suited to research concerning people living after 1930 because of legislated restrictions on records access for many or most areas.

You can try looking for city directories on the internet, but they are not likely to have direct linking information identifying children of a couple who married in 1925.

Have you looked for them in the 1930 US Census?
