After speaking to a number of Ogston's from around the world who have either had their Y-DNA tested or have had another male family member of Ogston decent perform a Y-DNA test, it appears as though the male Haplogroup for the Ogston family is G-M201 or more specifically subclade G2a2b2a1a1a1. These results also match the earliest known Ogston Y-DNA that has been recorded in the Scottish families research projects on FamilyTreeDNA.
Haplogroup G in Scotland is believed to represent the earliest inhabitants of the country, although some may have arrived with the Romans and later migrations. Haplogroups E and J are commonly thought to be more recent incomers to Scotland (last 1,000 years).
Haplogroup G-M201 geographic origins are estimated to be approximately 26,000 years ago in the mountainous regions nearby eastern Anatolia, Armenia or western Iran. Around 11,500 years ago the subclade G2a2b2a1a1a1 formed and migrated across Europe, etc.
Below is a brief snippet of information on haplogroup G2a2b2a1a1a1 from LivingDNA:
"Your fatherline is concentrated across the mountainous regions of Europe.
Your fatherline signature belongs to the G2a group.
Your fatherline has been associated with the migrations that occurred from the Near East to Europe during the Neolithic (New Stone Age). Around 11,500 years ago, haplogroup G2 split into two branches: G2a and G2b. G2b spread across Iran, whilst G2a travelled with its carriers across Anatolia and Europe. With the spread of agricultural technologies, practices and ideas came movements of people and populations. The populations that spread into Europe are thought to have carried the G2a fatherline with them, which helps explain the small presence of this haplogroup across Europe today. The high percentage of G2a found in samples from Neolithic burials suggests the carriers of this group played a significant role in Neolithic migrations across Europe some 6-8000 years ago (Lacan et al., 2011)."

If you would like to test your Y-DNA yourself, an affordable website that provides this service is LivingDNA and I would definitely recommend this for any person thinking about testing their DNA.
If you would like an even more in depth Y-DNA test then FamilyTreeDNA offers this service at varying levels, each a bit more expensive than the previous one. If you are interested in this then feel free to check it out.
