Meaning & History
There are several possible explanations for the meaning of the first element of this name. It could have been derived from Russian syroj or syroy (сырой) meaning "raw" (also compare Czech surový or syrový, which also means "raw"). An other explanation is that it is derived from Proto-Slavic širokъ meaning "wide, broad" (also compare Czech široký, which also means "wide, broad"). Lastly (but most unlikely), it could have been derived from Russian sirota or syrota (сирота) meaning "orphan" (compare Croatian sirotan and Polish sierota, both of which mean "orphan"). The second element of this name is derived from Slavic slav "glory".
