To 'match' someone with Y-DNA is a fuzzy thing, as many Y-DNA results will match many thousands to many millions of other males.
Just to clarify - I assume you are talking about STR results, not SNP's or haplogroups? Many of the yDNA haplogroups on WikiTree represent hundreds of millions of males (like the most popular one, R-M269).
And even with STR comparisons with 67 or higher markers, there can be dozens of matching males. There may be few that have tested yet, so it may only *appear* to be very few or only one match.
