since they married in 1897 and had 5 kids....give them 2 years before the first one is born and approx 2 years between the other 4....he probably went to US about 1910..
So when you click on that link check the 1910, 20 and 30 census records to see if he is listed in the index and where he lived at the time...then you can go from there
That site charges to see the actual records that would show who else is living in the household besides him but they have all the census records that are currently available to the public....
There are also a couple of links on there for free sites that have US census records but they dont have all the records that are currently available---but once you find out where he was from the index on the other site---you can check these free sites to see if they have the county records you need for those years...if so your in luck...if not you can always join the other one if you choose.
I found these four in UK on http://www.freebmd.org.uk/----sohttp://www.freebmd.org.uk/----so you can skip the 1910 US census mentioned above and just check 1920 and 1930
